Abstract: Background: The androgen receptor (AR) is expressed in >75% of hormone receptor (HR)+ tumors. AR signaling has been associated with resistance to endocrine therapy (ET). Aromatase inhibitors (AIs) divert estrogen precursors to androgens; in preclinical models enzalutamide (ENZA) blocked both estrogen- and androgen-mediated growth of HR+ cells. In a phase 1 study of ET+ENZA in breast cancer, doubling the dose of exemestane (EXE) to 50 mg was necessary to restore exposure observed with 25 mg.1 Methods: This placebo (PBO)–controlled phase 2 trial randomized patients (pts) with HR+/HER2-normal advanced/metastatic breast cancer (MBC) to either 25 mg EXE+PBO or 50 mg EXE+160 mg ENZA daily (NCT02007512). Two parallel cohorts enrolled pts who had no prior ET (C1) or who had received 1 prior ET for MBC (C2). Randomization was stratified on resistance to prior ET and prior exposure to AI. Tissue samples for biomarker development were mandatory. Brain metastases or a history of seizure was exclusionary. One prior chemotherapy regimen for MBC was permitted. Response was assessed every 8 weeks for 48 weeks, then every 12 weeks. Crossover to ENZA+EXE was allowed at disease progression. A gene signature–based biomarker (Bmkr) indicating AR signaling predictive of response to ENZA was developed using a training set of RNAseq data from 2/3 of randomized pts and validated using a test set of data from the remaining 1/3 of pts. Progression-free survival (PFS) according to RECIST v1.1 was the primary endpoint in the intent-to-treat (ITT) population and in the Bmkr+ subgroup of each cohort. Secondary endpoints included clinical benefit rate at 24 weeks (CBR24), best overall response, and safety. Results: A total of 247 pts were randomized (C1, n=127; C2, n=120). In C1, 50 pts (39.4%) were Bmkr+; in C2, 35 pts (29.2%) were Bmkr+. Statistically significant improvements in median PFS and CBR24 were observed only in the Bmkr+ population with no prior ET (Table). The most common adverse events (AEs) reported in the ENZA+EXE arms were nausea (39%) in C1 and fatigue (37%) in C2. In C1, 9 pts (15%) and 10 pts (16%) discontinued the study due to AEs in the ENZA+EXE and PBO+EXE arms, respectively. In C2, 11 pts (18%) and 5 pts (8%) discontinued due to AEs in the ENZA+EXE and PBO+EXE arms, respectively. Conclusions: In the first reported randomized trial of ENZA in HR+ MBC, ENZA+EXE was well tolerated with no new safety signals. The study met its primary endpoint in pts with Bmkr+ MBC with no prior ET. 1. Schwartzberg et al. Clin Cancer Res. 2017 Mar 9 [Epub ahead of print].

Abstract: Using data corresponding to an integrated luminosity of 79 pb-1, D0 has searched for events containing multiple jets and large missing transverse energy in pbar-p collisions at sqrt(s)=1.8 TeV at the Fermilab Tevatron collider. Observing no significant excess beyond what is expected from the standard model, we set limits on the masses of squarks and gluinos and on the model parameters m_0 and m_1/2, in the framework of the minimal low-energy supergravity models of supersymmetry. For tan(beta) = 2 and A_0 = 0, with mu < 0, we exclude all models with m_squark < 250 GeV/c^2. For models with equal squark and gluino masses, we exclude m < 260 GeV/c^2., 10 pages, 3 figures, Submitted to PRL, Fixed typo on page bottom of p. 6 (QCD multijet background is 35.4 events)

Abstract: We present results on dijet production via hard color-singlet exchange in proton-antiproton collisions at √s = 630 GeV and 1800 GeV using the DØ detector. The fraction of dijet events produced via color-singlet exchange is measured as a function of jet transverse energy, separation in pseudorapidity between the two highest transverse energy jets, and proton-antiproton center-of-mass energy. The results are consistent with a color-singlet fraction that increases with an increasing fraction of quark-initiated processes and inconsistent with two-gluon models for the hard color-singlet. © 1998 Published by Elsevier Science B.V.

Abstract: We present a measurement of the Drell-Yan cross section at high dielectron invariant mass using 120/pb of data collected in pbar-p collisions at sqrt(s) = 1.8 TeV by the D0 collaboration during 1992-96. No deviation from standard model expectations is observed. We use the data to set limits on the energy scale of quark-electron compositeness with common constituents. The 95% confidence level lower limits on the compositeness scale vary between 3.3 TeV and 6.1 TeV depending on the assumed form of the effective contact interaction., 6 pages, 2 figures, submitted to PRL

Abstract: The DZERO detector is used to study proton-antiproton collisions at the 1800 GeV and 630 GeV center-of-mass energies available at the Fermilab Tevatron. To measure jets, the detector uses a sampling calorimeter composed of uranium and liquid argon as the passive and active media respectively. Understanding the jet energy calibration is not only crucial for precision tests of QCD, but also for the measurement of particle masses and the determination of physics backgrounds associated with new phenomena. This paper describes the energy calibration of jets observed with the DZERO detector at the two proton-antiproton center-of-mass energies in the transverse energy and pseudorapidity range ET>8 GeV and pseudorapidity, 94 pages with 52 figures (included in the 94 pages)

Abstract: To investigate the effect of acid etching procedure on the remineralisation of white spot lesions (WSL) which had undergone an initial phase of arrest, and to compare between the effect of fluoride and/or CPP-ACP on remineralisation before and after acid etching.In vitro study.WSL were prepared in vitro on 130 human enamel slabs which were allocated into four experimental groups (N = 30) and one control group (N = 10). Changes in mineral content were registered weekly by Quantitative Light Induced Fluorescence QLF. When changes had arrested (after 8 weeks), the enamel surface of 20 slabs in each group were acid etched. The remineralisation process was continued until it slowed down again (after 5 weeks).Mean fluorescence gain was 13.7 ± 0.9% in the fluoride group, 16.5 ± 1.1% in the CPP-ACP group, and 11.4 ± 1.2% in the combination of fluoride and CPP-ACP group.There was a tendency toward better remineralisation after acid etching but this did not reach a significant level; the effect of etching was more pronounced in the presence of fluoride. Although CPP-ACP seemed to give a steadier rate of remineralisation over time when compared with fluoride, the overall remineralisation in the regimens was similar. In this model, combined treatment of fluoride and CPP-ACP did not have an extra benefit over the fluoride or CPP-ACP alone.

Abstract: The D0 collaboration has performed a study of spin correlation in tt-bar production for the process tt-bar to bb-bar W^+W^-, where the W bosons decay to e-nu or mu-nu. A sample of six events was collected during an exposure of the D0 detector to an integrated luminosity of approximately 125 pb^-1 of sqrt{s}=1.8 TeV pp-bar collisions. The standard model (SM) predicts that the short lifetime of the top quark ensures the transmission of any spin information at production to the tt-bar decay products. The degree of spin correlation is characterized by a correlation coefficient k. We find that k>-0.25 at the 68% confidence level, in agreement with the SM prediction of k=0.88.

Abstract: of data collected with the DO detector during 1993-1995. We find that a(p (p) over bar --> W + X)B(W --> tau nu) = 2.22 +/- 0.09 (stat) +/- 0.10 (syst) +/- 0.10 (lum) nb. Lepton universality predicts that the ratio of the tau and electron electroweak charged current couplings to the W boson, g(T)(W)/g(e)(W), be unity. We find g(T)(W)/g(e)(W) = 0.980 +/- 0.031, in agreement with lepton universality.

Abstract: Inclusive dijet production at large pseudorapidity intervals (Delta eta) between the two jets has been suggested as a regime for observing Balitsky-Fadin-Kuraev-Lipatov (BFKL) dynamics. We have measured the dijet cross section for large Delta eta in p (p) over bar collisions at root s = 1800 and 630 GeV using the D0 detector. The partonic cross section increases strongly with the size of Delta eta; The observed growth is even stronger than expected on the basis of BFKL resummation in the leading logarithmic approximation. The growth of the partonic cross section can be accommodated with an effective BFKL intercept of alpha(BFKL)(20 GeV) = 1.65 +/- 0.07.

Abstract: This Letter describes a measurement of the muon cross section originating from b quark decay in the forward rapidity range 2.4 < y(mu) < 3.2 in pbarp collisions at sqrt(s) = 1.8 TeV. The data used in this analysis were collected by the D0 experiment at the Fermilab Tevatron. We find that NLO QCD calculations underestimate b quark production by a factor of four in the forward rapidity region. A cross section measurement using muon+jet data has been included in this version of the paper.

Abstract: We present a measurement of the transverse momentum distribution of Z bosons produced in ppbar collisions at sqrt{s}=1.8 TeV using data collected by the D0 experiment at the Fermilab Tevatron Collider during 1994--1996. We find good agreement between our data and a current resummation calculation. We also use our data to extract values of the non-perturbative parameters for a particular version of the resummation formalism, obtaining significantly more precise values than previous determinations.

Abstract: We report on a search for second generation leptoquarks (LQ) produced in p (p) over bar collisions at root s = 1.8 TeV using the DO detector at Fermilab. Second generation leptoquarks are assumed to be produced in pairs and to decay to either mu. or nu and either a strange or a charm quark (q). Limits an placed on sigma(p (p) over bar --> LQ --> mu nu + jets) as a function of the mass of the leptoquark. For equal branching ratios to mu q and nu q, second generation scalar leptoquarks with a mass below 160 GeV/c(2), vector leptoquarks with anomalous minimal vector couplings with a mass below 240 GeV/c(2), and vector leptoquarks with Yang-Mills couplings with a mass below 290 GeV/c(2), are excluded at the 95% confidence level.

Abstract: Using the DZero detector at the 1.8 TeV pbarp Fermilab Tevatron collider, we have measured the inclusive dijet mass spectrum in the central pseudorapidity region |eta_jet| < 1.0 for dijet masses greater than 200 Gev/c^2. We have also measured the ratio of spectra sigma(|eta_jet| < 0.5)/sigma(0.5 < |eta_jet| < 1.0). The order alpha_s^3 QCD predictions are in good agreement with the data and we rule out models of quark compositeness with a contact interaction scale < 2.4 TeV at the 95% confidence level.

Abstract: We search for new physics using events with one high transverse energy photon, two or more jets, and an apparent imbalance in transverse energy, in p{ovr p} collisions at the Fermilab Tevatron at {radical} (s) =1.8 TeV . Such events are predicted for production of supersymmetric particles in some models. No excess is observed beyond expected background. For the parameter space of the minimal supersymmetric standard model with branching fraction B({tilde {chi}}{sup 0}{sub 2}{r_arrow}{gamma}thinsp{tilde {chi}}{sup 0}{sub 1})=1 and m{sub {tilde {chi}}{sup 0}{sub 2 }}{minus}m{sub {tilde {chi}}{sup 0}{sub 1}}{gt}20 GeV , we obtain a 95{percent} confidence level lower mass limit of 310thinspthinspGeV for equal mass squarks and gluinos. The results are also interpreted in models with low energy gauge mediated supersymmetry breaking. {copyright} {ital 1998} {ital The American Physical Society }

Abstract: We report on a search for $\mathrm{charge}\ensuremath{-}1/3$ third-generation leptoquarks (LQ) produced in $p\overline{p}$ collisions at $\ensuremath{\surd}s\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8\mathrm{TeV}$ using the $\mathrm{D}0$ detector at Fermilab. Third-generation leptoquarks are assumed to be produced in pairs and to decay to a tau neutrino and a $b$ quark with branching fraction $B$. We place upper limits on $\ensuremath{\sigma}(p\overline{p}\ensuremath{\rightarrow}\mathrm{LQ}\overline{\mathrm{LQ}}){B}^{2}$ as a function of the leptoquark mass ${M}_{\mathrm{LQ}}$. Assuming $B\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1$, we exclude at the 95% confidence level third-generation scalar leptoquarks with ${M}_{\mathrm{LQ}}l94\mathrm{GeV}{/c}^{2}$, and third-generation vector leptoquarks with ${M}_{\mathrm{LQ}}l216\mathrm{GeV}{/c}^{2}({M}_{\mathrm{LQ}}l148\mathrm{GeV}{/c}^{2}$) assuming Yang-Mills (anomalous) coupling.

Abstract: The shape of the transverse momentum distribution of W bosons (p_T(W)) produced in pbarp collisions at sqrt(s)= 1.8 TeV is measured with the DO detector at Fermilab. The result is compared to QCD perturbative and resummation calculations over the p_T(W) range from 0-200 GeV/c. The shape of the distribution is consistent with the theoretical prediction.

Abstract: We report a measurement of the W boson mass based on an integrated luminosity of 82 pb −1 from pp collisions at √s = 1.8 TeV recorded in 1994-1995 by the D0 detector at the Fermilab Tevatron. We identify W bosons by their decays to e∨ V and extract the mass by fitting the transverse mass spectrum from 28 323 W boson candidates. A sample of 3563 dielectron events, mostly due to Z→ee decays, constrains models of W boson production and the detector. We measure M W = 80.44±0.10(stat)±0.07(syst) GeV. By combining this measurement with our result form the 1992-1993 data set, we obtain M W = 80.43±0.11 GeV.

Abstract: We have searched for first generation scalar leptoquark (LQ) pairs in the enu+jets channel using ppbar collider data (integrated luminosity= 115 pb^-1) collected by the DZero experiment at the Fermilab Tevatron during 1992-96. The analysis yields no candidate events. We combine the results with those from the ee+jets and nunu+jets channels to obtain 95% confidence level (CL) upper limits on the LQ pair production cross section as a function of mass and of beta, the branching fraction to a charged lepton. Comparing with the next-to-leading order theory, we set 95% CL lower limits on the LQ mass of 225, 204, and 79 GeV/c^2 for beta=1, 1/2, and 0, respectively.

Abstract: We have searched for the flavor-changing neutral current decay b -> s mu+ mu- in p pbar collisions at sqrt(s) = 1.8 TeV with the DO detector at Fermilab. We determine the 90% confidence level limit for the branching fraction to be B(b -> X_s mu+ mu-) < 3.2 x 10^{-4}. We argue that this limit is more stringent than the best published limit on this decay rate.

Abstract: We have searched for the pair production of first generation scalar leptoquarks in the $\mathrm{eejj}$ channel using the full data set $(123{\mathrm{pb}}^{\ensuremath{-}1})$ collected with the D0 detector at the Fermilab Tevatron during 1992--1996. We observe no candidates with an expected background of approximately 0.4 events. Comparing the experimental 95% confidence level upper limit to theoretical calculations of the cross section with the assumption of a 100% branching fraction of $\mathrm{eq}$, we set a lower limit on the mass of a first generation scalar leptoquark of $225\mathrm{GeV}{/c}^{2}$. The results of this analysis rule out the interpretation of the excess of high ${Q}^{2}$ events at DESY HERA as leptoquarks which decay exclusively to $\mathrm{eq}$.

Abstract: We present a measurement of the ttbar production cross section in ppbar collisions at root(s) = 1.8TeV by the D0 experiment at the Fermilab Tevatron. The measurement is based on data from an integrated luminosity of approximately 125 pb^-1 accumulated during the 1992-1996 collider run. We observe 39 ttbar candidate events in the dilepton and lepton+jets decay channels with an expected background of 13.7+-2.2 events. For a top quark mass of 173.3GeV/c^2, we measure the ttbar production cross section to be 5.5+-1.8 pb.

Abstract: We have measured the $\mathrm{WW}\ensuremath{\gamma}$ gauge boson coupling parameters using $p\overline{p}\ensuremath{\rightarrow}\ensuremath{\ell}\ensuremath{\nu}\ensuremath{\gamma}+X$ ( $\ensuremath{\ell}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}e,\ensuremath{\mu}$) events at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8$ TeV. The data, corresponding to an integrated luminosity of $92.8{\mathrm{pb}}^{\ensuremath{-}1}$, were collected using the D\O{} detector at the Fermilab Tevatron Collider. The measured cross section times branching ratio for $p\overline{p}\ensuremath{\rightarrow}W\ensuremath{\gamma}+X$ with ${p}_{T}^{\ensuremath{\gamma}}g10$ GeV/c and ${R}_{\ensuremath{\ell}\ensuremath{\gamma}}g0.7$ is ${11.3}_{\ensuremath{-}1.5}^{+1.7}\ifmmode\pm\else\textpm\fi{}1.5$ pb, in agreement with the standard model prediction. The 1 degree of freedom 95% confidence level limits on individual CP-conserving parameters are $\ensuremath{-}0.93l\ensuremath{\Delta}\ensuremath{\kappa}l0.94$ and $\ensuremath{-}0.31l\ensuremath{\lambda}l0.29$. Similar limits are set on the CP-violating coupling parameters.

Abstract: A search for new physics has been carried out in the channel pp→γγ+E T , as expected in various supersymmetric models. We require two photons with transverse energy E T γ >12GeV and pseudorapidity |η γ | T ) is consistent with background and no events have E T >25GeV. We set limits on production cross sections for selectron, sneutrino, and neutralino pairs, decaying into photons, which range from about 400 fb to 1 pb depending on the sparticle masses. A general limit of 185 fb (95% C.L.) is set on σ(pp→γγE T +X), where E T γ >12GeV, |η γ | T >25GeV.

Abstract: A measurement of the cross section for production of single, isolated photons is reported for transverse energies in the range of 10–125 GeV for two regions of pseudorapidity, |η| -1 of integrated luminosity accumulated in pp collisions at √s=1.8TeV and recorded with the D0 detector at the Fermilab Tevatron Collider. The background, predominantly from jets which fragment to neutral mesons, is estimated using the longitudinal shower shape in the calorimeter. In both pseudorapidity regions the cross section is found to agree with the next-to-leading order QCD prediction for 30≲E T γ ≲80GeV.

Abstract: We present results from a search for anomalous $\mathrm{WW}$ and $\mathrm{WZ}$ production in $p\overline{p}$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8\phantom{\rule{0ex}{0ex}}\mathrm{TeV}$. We used $p\overline{p}\ensuremath{\rightarrow}e\ensuremath{\nu}\mathrm{jjX}$ events observed during the 1992--1993 run of the Fermilab Tevatron collider, corresponding to an integrated luminosity of $13.7\ifmmode\pm\else\textpm\fi{}0.7{\mathrm{pb}}^{\ensuremath{-}1}$. A fit to the transverse momentum spectrum of the $W$ boson yields direct limits on the CP-conserving anomalous $\mathrm{WW}\ensuremath{\gamma}$ and $\mathrm{WWZ}$ coupling parameters of $\ensuremath{-}0.9l\ensuremath{\Delta}\ensuremath{\kappa}l1.1$ (with $\ensuremath{\lambda}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0$) and $\ensuremath{-}0.6l\ensuremath{\lambda}l0.7$ (with $\ensuremath{\Delta}\ensuremath{\kappa}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0$) at the 95% confidence level, for a form factor scale $\ensuremath{\Lambda}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.5\phantom{\rule{0ex}{0ex}}\mathrm{TeV}$, assuming that the $\mathrm{WW}\ensuremath{\gamma}$ and $\mathrm{WWZ}$ coupling parameters are equal.

Abstract: The global topologies of inclusive three- and four-jet events produced in $\overline{p}p$ interactions are described. The three- and four-jet events are selected from data recorded by the D0 detector at the Fermilab Tevatron Collider operating at a center-of-mass energy of $\sqrt{s}=1800$ GeV. The measured, normalized distributions of various topological variables are compared with parton-level predictions of tree-level QCD calculations. The parton-level QCD calculations are found to be in good agreement with the data. The studies also show that the topological distributions of the different subprocesses involving different numbers of quarks are very similar and reproduce the measured distributions well. The parton-shower Monte Carlo generators provide a less satisfactory description of the topologies of the three- and four-jet events.

Abstract: We report on a search for right-handed W bosons (W R ) with mass greater than 200GeV/c 2 . We used data collected with the D0 detector at the Fermilab Tevatron pp collider at √s=1.8TeV to search for W R decays into an electron and a massive right-handed neutrino W R ± >e ± N R . Using the inclusive electron data, we set mass limits independent of the N R decay: m W R >650GeV/c 2 and m W R >720GeV/c 2 at the 95% confidence level, valid for m N R W R and mN R «m W R , respectively. The latter also represents a new lower limit on the mass of a heavy left-handed W boson (W') decaying into ev. In addition, limits on mWR valid for larger values of the N R mass are obtained assuming that NR decays to an electron and two jets.

Abstract: We have searched for associated production of the lightest chargino W 1 and next-to-lightest neutralino Z 2 of the minimal supersymmetric standard model in pp collisions at √s=1.8 TeV using the D0 detector at the Fermilab Tevatron collider. Data corresponding to an integrated luminosity of 12.5±0.7pb -1 were examined for events containing three isolated leptons. No evidence for W 1 Z 2 pair production was found. Limits on s(W 1 Z 2 )B(W 1 →lνZ 1 )B(Z 2 →llZ 1 ) are presented.

Abstract: We present a search for pair produced top squarks, the supersymmetric partners of the top quark, using the D0 detector at the Fermilab Tevatron pp collider. We consider a scenario in which the lighter of the two top squarks t 1 decays with 100% branching fraction to a charm quark and the lightest neutralino χ 1 0 yielding a signal of two acollinear jets with missing transverse energy. We observe 3 events while we expect 3.5±1.2 events from the known standard model processes. We exclude at the 95% confidence level a significant region of the m t 1 - m χ 1 0 parameter space. The highest m t 1 value we exclude is 93 GeV/c 2 with a corresponding m χ 1 0 value of 8 GeV/c 2 .

Abstract: We have studied J ψ production in p p collisions at s = 1.8 TeV with the DO detector at Fermilab using μ+μ− data. We have measured the inclusive J ψ production cross section as a function of J ψ transverse momentum, pT. For the kinematic range pT > 8 GeV/c and |η| σ(p p → J ψ + X) · Br ( J ψ → μ + μ − ) = 2.08 ± 0.17( stat) ± 0.46(syst) nb. Using the muon impact parameter we have estimated the fraction of J ψ mesons coming from B meson decays to be fb = 0.35 ± 0.09(stat)±0.10(syst) and inferred the inclusive b production cross section. From the information on the event topology the fraction of nonisolated J ψ events has been measured to be fnonisol = 0.64 ± 0.08(stat)±0.06(syst). We have also obtained the fraction of J ψ events resulting from radiative decays of χc states, fχ = 0.32 ± 0.07(stat)±0.07(syst). We discuss the implications of our measurements for charmonium production processes.

Abstract: A study of the particle multiplicity between jets with large rapidity separation has been performed using the D\O\ detector at the Fermilab Tevatron $p\bar{p}$ Collider operating at $\sqrt{s}=1.8$\,TeV. A significant excess of low-multiplicity events is observed above the expectation for color-exchange processes. The measured fractional excess is $1.07 \pm 0.10({\rm stat})~{ + 0.25}_{- 0.13}({\rm syst})\%$, which is consistent with a strongly-interacting color-singlet (colorless) exchange process and cannot be explained by electroweak exchange alone. A lower limit of $0.80\%$ (95\% C.L.) is obtained on the fraction of dijet events with color-singlet exchange, independent of the rapidity gap survival probability.

Abstract: We report on a search for second generation scalar leptoquarks with the D0 detector at the Fermilab Tevatron pp collider at √s = 1.8 TeV. This search is based on 12.7 pb-1 of data. Second generation leptoquarks are assumed to be produced in pairs and to decay into a neutrino and quark with branching ratio β or into a neutrino and quark with branching ratio 1 - β. We obtain cross section times branching ratio limits as a function of leptoquark mass and set lower limits on the leptoquark mass at the 95% confidence level.

Abstract: The ratio of the number of {ital W}+1 jet to {ital W}+0 jet events is measured with the D0 detector using data from the 1992--93 Tevatron Collider run. For the {ital W}{r_arrow}{ital e}{nu} channel with a minimum jet {ital E}{sub {ital T}} cutoff of 25 GeV, the experimental ratio is 0.065{plus_minus}0.003(stat){plus_minus}0.007(syst). Next-to-leading order QCD predictions for various parton distributions agree well with each other and are all over 1 standard deviation below the measurement. Varying the strong coupling constant {alpha}{sub {ital s}} in both the parton distributions and the partonic cross sections simultaneously does not remove this discrepancy. {copyright} {ital 1995} {ital The} {ital American} {ital Physical} {ital Society}.

Abstract: The distribution of the transverse energy in jets has been measured in p p collisions at s =1.8 TeV TeV using the DO detector at Fermilab. This measurement of the jet shape is made as a function of jet transverse energy in both the central and forward rapidity regions. Jets are shown to narrow both with increasing transverse energy and with increasing rapidity. Next-to-leading order partonic QCD calculations are compared to the data. Although the calculations qualitatively describe the data, they are shown to be very dependent on renormalization scale, parton clustering algorithm, and jet direction definition and they fail to describe the data in all regions consistently.

Abstract: A search for a heavy charged gauge boson, W′, using the decay channels W′ → eν and W′ → τν → eνν ν is reported. The data used in the analysis were collected by the DO experiment at the Fermilab Tevatron during the 1992-93 p p collider run from an integrated luminosity of 13.9 ± 0.8 pb−1 at s =1.8 TeV . Assuming that the neutrino from W′ decay is stable and has a mass significantly less than mW′, an upper limit at the 95% confidence level is set on the cross section times branching ratio for p p → W′ → eν . A W′ with the same couplings to quarks and leptons as the standard model W boson is excluded for mW′

Abstract: The inclusive cross sections times leptonic branching ratios for $W$ and $Z$ boson production in $p\overline{p}$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8$ TeV were measured using the D0 detector at the Fermilab Tevatron collider: ${\ensuremath{\sigma}}_{W}B(W\ensuremath{\rightarrow}e\ensuremath{\nu})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2.36\ifmmode\pm\else\textpm\fi{}0.07\ifmmode\pm\else\textpm\fi{}0.13\mathrm{nb}$, ${\ensuremath{\sigma}}_{W}B\left(W\ensuremath{\rightarrow}\ensuremath{\mu}\ensuremath{\nu}\right)\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2.09\ifmmode\pm\else\textpm\fi{}0.23\ifmmode\pm\else\textpm\fi{}0.11\mathrm{nb}$, ${\ensuremath{\sigma}}_{Z}B\left(Z\ensuremath{\rightarrow}{e}^{+}{e}^{\ensuremath{-}}\right)\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.218\ifmmode\pm\else\textpm\fi{}0.011\ifmmode\pm\else\textpm\fi{}0.012\mathrm{nb}$, and ${\ensuremath{\sigma}}_{Z}B\left(Z\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}\right)\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.178\ifmmode\pm\else\textpm\fi{}0.030\ifmmode\pm\else\textpm\fi{}0.009\mathrm{nb}$. The first error is the combined statistical and systematic uncertainty, and the second reflects the uncertainty in the luminosity. For the combined electron and muon analyses we find ${\ensuremath{\sigma}}_{W}B(W\ensuremath{\rightarrow}l\ensuremath{\nu})/{\ensuremath{\sigma}}_{Z}B(Z\ensuremath{\rightarrow}{l}^{+}{l}^{\ensuremath{-}})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}10.90\ifmmode\pm\else\textpm\fi{}0.49$. Assuming standard model couplings, this result is used to determine the width of the $W$ boson, $\ensuremath{\gamma}(W)\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2.044\ifmmode\pm\else\textpm\fi{}0.093\mathrm{GeV}$.

Abstract: We performed a direct search for the anomalous {ital ZZ}{gamma} and {ital Z}{gamma}{gamma} couplings by studying {ital p{bar p}}{r_arrow}ll{gamma}+{ital X} (l={ital e},{mu}) events at {radical}{ital s}=1.8 TeV with the D0 detector at the Fermilab Tevatron Collider. A fit to the transverse energy spectrum of the photon in the signal events, based on the data set corresponding to an integrated luminosity of 14.3pb{sup {minus}1} (13.7pb{sup {minus}1}) for the electron (muon) channel, yields the following 95% confidence level limits on the anomalous {ital CP}-conserving {ital ZZ}{gamma} couplings: {vert_bar}{ital h}{sub 30}{sup {ital Z}}{vert_bar}{lt}1.8 ({ital h}{sub 40}{sup {ital Z}}=0) and {vert_bar}{ital h}{sub 40}{sup {ital Z}}{vert_bar}{lt}0.5 ({ital h}{sub 30}{sup {ital Z}}=0), for a form-factor scale {Lambda}=500 GeV. Limits for the {ital Z}{gamma}{gamma} couplings and {ital CP}-violating couplings are also discussed.

Abstract: The {ital WW}{gamma} gauge boson couplings were measured using {ital p{bar p}}{r_arrow}l{nu}{gamma}+{ital X} (l={ital e},{mu}) events at {radical}{ital s}=1.8 TeV observed with the D0 detector at the Fermilab Tevatron Collider. The signal, obtained from the data corresponding to an integrated luminosity of 13.8pb{sup {minus}1}, agrees well with the standard model prediction. A fit to the photon transverse energy spectrum yields limits at the 95% confidence level on the {ital CP}-conserving anomalous coupling parameters of {minus}1.6{lt}{Delta}{kappa}{lt}1.8 ({lambda}=0) and {minus}0.6{lt}{lambda}{lt}0.6 ({Delta}{kappa}=0). Similar limits are obtained for the {ital CP}-violating coupling parameters.

Abstract: The results of a search for W boson pair production in p{bar p} collisions at {radical}s = 1.8 TeV with subsequent decay to dilepton (e{mu}, ee, and {mu}{mu}) channels are presented. One event is observed with an expected background of 0.56 {plus_minus} 0.13 events with an integrated luminosity of approximately 14 pb{sup {minus}1}. Assuming equal strengths for the WWZ and WW{gamma} gauge boson coupling parameters {kappa} and {lambda}, limits on the CP-conserving anomalous coupling constants are {minus}2.6 < {delta}{kappa} < 2.8 and {minus}2.1 {lambda} < 2.1 at the 95% confidence level.

Abstract: We present a search for events consistent with the production and decay of the squarks and gluinos of the minimal supersymmetric standard model (MSSM) in the D0 detector at the Fermilab Tevatron {ital p{bar p}} collider. We examined data for events containing large missing transverse energy and three or more jets. We observed no excess of events above the expected yield from standard model processes. For a choice of MSSM parameter values, we set a lower limit at the 95% confidence level on the mass of the gluino of 144 GeV/{ital c}{sup 2} for all squark masses and a lower limit of 212 GeV/{ital c}{sup 2} for equal squark and gluino masses.

Abstract: We present a measurement of the inclusive jet cross section in {ital {bar p}p} collisions at {radical}{ital s} =1.8 TeV at the Fermilab Tevatron using the Collider Detector at Fermilab. Good agreement is seen with the predictions of recent next-to-leading-order ({ital O}({alpha}{sub {ital s}}{sup 3})) QCD predictions. The dependence of the cross section on clustering cone size is reported for the first time. An improved limit on {Lambda}{sub {ital c}}, a term characterizing possible quark substructure, is set at 1.4 TeV (95% C.L.).

Abstract: Limits on anomalous $\mathrm{WW}\ensuremath{\gamma}$ and $\mathrm{WWZ}$ couplings are presented from a study of $WW/W\stackrel{\ensuremath{\rightarrow}}{Z}e\ensuremath{\nu}\mathrm{jj}$ events produced in $p\overline{p}$ collisions at $\sqrt{s}=1.8 \mathrm{TeV}.$ Results from the analysis of data collected using the D\O{} detector during the 1993--1995 Tevatron collider run at Fermilab are combined with those of an earlier study from the 1992--1993 run. A fit to the transverse momentum spectrum of the W boson yields direct limits on anomalous $\mathrm{WW}\ensuremath{\gamma}$ and $\mathrm{WWZ}$ couplings. With the assumption that the $\mathrm{WW}\ensuremath{\gamma}$ and $\mathrm{WWZ}$ couplings are equal, we obtain $\ensuremath{-}0.34l\ensuremath{\lambda}l0.36$ (with $\ensuremath{\Delta}\ensuremath{\kappa}=0)$ and $\ensuremath{-}0.43l\ensuremath{\Delta}\ensuremath{\kappa}l0.59$ (with $\ensuremath{\lambda}=0)$ at the 95% confidence level for a form-factor scale $\ensuremath{\Lambda}=2.0 \mathrm{TeV}.$

Abstract: Inclusive dijet production at large pseudorapidity intervals (Deltaeta) between the two jets has been suggested as a regime for observing Balitsky-Fadin-Kuraev-Lipatov (BFKL) dynamics. We have measured the dijet cross section for large Deltaeta in pp collisions at sqrt[s]=1800 and 630 GeV using the D0 detector. The partonic cross section increases strongly with the size of Deltaeta. The observed growth is even stronger than expected on the basis of BFKL resummation in the leading logarithmic approximation. The growth of the partonic cross section can be accommodated with an effective BFKL intercept of alphaBFKL(20 GeV)=1.65+/-0.07.

Abstract: We report on measurements on inclusive cross sections times branching fractions into electrons for W and Z bosons produced in p (p) over bar collisions at root s = 1.8 TeV. From an integrated luminosity of 84.5 pb(-1) recorded in 1994-1995 using the D empty set detector at the Fermilab Tevatron, we determine sigma(p (p) over bar--> W + X) x B(W-->e nu) = 2310 +/- 10(stat) +/- 50(syst) +/- 100(lum)pb and sigma(p (p) over bar-->Z + X) x B(Z-->ee)=221+/-3(stat)+/-4(syst)+/-10(lum)pb. From these, we derive sigma(p (p) over bar-->W + X) x B(N-->e nu)/sigma(p (p) over bar-->Z + X) x B(Z-->ee) = 10.43+/-0.15(stat) +/- 0.20(syst) +/- 0.10(NLO), B(W-->e nu) = 0.1044+/-0.0015(stat)+/-0.0020(syst)+/-0.0017(theory)+/-0.0010(NLO). and Gamma(w) = 2169 +/- 0.03 l(stat) +/- 0.042(syst) +/- 0.041(theory)+/- 0.022(NLO)GeV. We use the latter to set a 95% confidence level upper limit on the partial decay width of the W boson into nonstandard model final states, Gamma(W)(inv), of 0.213 GeV. Combining these results with those from the 1992-1993 data gives sigma(p (p) over bar-->W+X) x B(W-->e nu)/sigma(p (p) over bar-->Z+X) x B(Z-->ee) = 10.51+/-0.25, Gamma(W) = 2.152 +/- 0.066 GeV, and a 95% C.L. upper limit an Gamma(W)(inv) of 0.191 GeV. Using a sample with a luminosity of 505 nb(-1) taken at root s = 630 GeV, we measure sigma(p (p) over bar--> W+ X) x B(W --> e nu) = 658 +/- 67 pb.

Abstract: We present a measurement of the differential cross section as a function of transverse momentum of the Z boson in ppbar collisions at sqrt{s}=1.8 TeV using data collected by the D0 experiment at the Fermilab Tevatron Collider during 1994--1996. We find good agreement between our data and the NNLO resummation prediction and extract values of the non-perturbative parameters for the resummed prediction from a fit to the differential cross section.
