Abstract

We present measurements of correlated $b\overline{b}$ cross sections, $\ensuremath{\mu}\ensuremath{-}\ensuremath{\mu}$ correlations, the average ${B}^{0}{\overline{B}}^{0}$ mixing parameter $\overline{\ensuremath{\chi}}$, and a limit on the CP-violating parameter ${\ensuremath{\epsilon}}_{B}.$ For these measurements, we use muon pairs from $b\overline{b}$ double semileptonic decays. The data used in this analysis were taken with the Collider Detector at Fermilab and represent an integrated luminosity of $17.4\ifmmode\pm\else\textpm\fi{}0.6$ pb${}^{\ensuremath{-}1}$. The results concerning $b\overline{b}$ production correlations are compared to predictions of next-to-leading order QCD computations.

Abstract

We report a measurement of the ratios of the decay rates of the ${B}^{+}$, ${B}^{0}$, and ${B}_{s}^{0}$ mesons into exclusive final states containing a $\frac{J}{\ensuremath{\psi}}$ meson. The final states were selected from 19.6 pb-1 of $p\overline{p}$ collisions recorded by the Collider Detector at Fermilab. These data are interpreted to determine the $b$ quark fragmentation fractions ${f}_{u}$, ${f}_{d}$, and ${f}_{s}$. We also determine the branching fractions for the decay modes ${B}^{+}\ensuremath{\rightarrow}\frac{J}{\ensuremath{\psi}{K}^{+}}$, ${B}^{+}\ensuremath{\rightarrow}\frac{J}{\ensuremath{\psi}{K}^{*}{(892)}^{+}}$, ${B}^{0}\ensuremath{\rightarrow}\frac{J}{\ensuremath{\psi}{K}^{0}}$, ${B}^{0}\ensuremath{\rightarrow}\frac{J}{\ensuremath{\psi}{K}^{*}{(892)}^{0}}$, and ${B}_{s}^{0}\ensuremath{\rightarrow}\frac{J}{\ensuremath{\psi}\ensuremath{\varphi}(1020)}$. We discuss the implications of these measurements to $B$ meson decay models.

Abstract

We measure the mass of the ${\mathit{B}}_{\mathit{s}}^{0}$ meson by reconstructing the decay chain ${\mathit{B}}_{\mathit{s}}^{0}$\ensuremath{\rightarrow}J/\ensuremath{\psi}\ensuremath{\varphi}, J/\ensuremath{\psi}\ensuremath{\rightarrow}${\mathrm{\ensuremath{\mu}}}^{+}$${\mathrm{\ensuremath{\mu}}}^{\mathrm{\ensuremath{-}}}$, and \ensuremath{\varphi}\ensuremath{\rightarrow}${\mathit{K}}^{+}$${\mathit{K}}^{\mathrm{\ensuremath{-}}}$. The data are obtained from 19.3 ${\mathrm{pb}}^{\mathrm{\ensuremath{-}}1}$ of integrated luminosity of p\ifmmode\bar\else\textasciimacron\fi{}p collisions at \ensuremath{\surd}s=1.8 TeV using the Collider Detector at Fermilab. A sample of 80 000 inclusive J/\ensuremath{\psi}\ensuremath{\rightarrow}${\mathrm{\ensuremath{\mu}}}^{+}$${\mathrm{\ensuremath{\mu}}}^{\mathrm{\ensuremath{-}}}$ events is used to study systematic biases in track reconstruction and to calibrate the momentum scale. We reconstruct the kinematically similar decays ${\mathit{B}}^{+}$\ensuremath{\rightarrow}J/\ensuremath{\psi}${\mathit{K}}^{+}$ and ${\mathit{B}}^{0}$\ensuremath{\rightarrow}J/\ensuremath{\psi}${\mathit{K}}^{\mathrm{*}0}$ to study the mass measurement technique used for the ${\mathit{B}}_{\mathit{s}}^{0}$ meson. Based on the observation of 32 \ifmmode\pm\else\textpm\fi{} 6 candidates, the mass of the ${\mathit{B}}_{\mathit{s}}^{0}$ meson is measured to be 5369.9 \ifmmode\pm\else\textpm\fi{} 2.3 \ifmmode\pm\else\textpm\fi{} 1.3 MeV/${\mathit{c}}^{2}$ and the mass difference between ${\mathit{B}}_{\mathit{s}}^{0}$ and the average mass of ${\mathit{B}}^{+}$ and ${\mathit{B}}^{0}$ is determined to be 89.7 \ifmmode\pm\else\textpm\fi{} 2.7 \ifmmode\pm\else\textpm\fi{} 1.2 MeV/${\mathit{c}}^{2}$. \textcopyright{} 1996 The American Physical Society.

Abstract

Artículo escrito por un elevado número de autores, solo se referencian el que aparece en primer lugar, el nombre del grupo de colaboración, si le hubiere, y los autores pertenecientes a la UAM, Three-jet production in deep inelastic ep scattering and photoproduction was investigated with the ZEUS detector at HERA using an integrated luminosity of up to 127pb-1. Measurements of differential cross sections are presented as functions of angular correlations between the three jets in the final state and the proton-beam direction. These correlations provide a stringent test of perturbative QCD and show sensitivity to the contributions from different color configurations. Fixed-order perturbative calculations assuming the values of the color factors CF, CA, and TF as derived from a variety of gauge groups were compared to the measurements to study the underlying gauge group symmetry. The measured angular correlations in the deep inelastic ep scattering and photoproduction regimes are consistent with the admixture of color configurations as predicted by SU(3) and disfavour other symmetry groups, such as SU(N) in the limit of large N, This work was supported by the U.S. Department of Energy, the Italian National Institute for Nuclear Physics (INFN), the German Federal Ministry for Education and Research (BMBF) under Contract No. H09PDF, No. 05h09GUF, and the SFB 676 of the Deutsche Forschungsgemeinschaft (DFG); DESY, Germany; the Science and Technology Facilities Council, United Kingdom; an FRGS grant from the Malaysian government; Presidential grant N-4142.2010.2 for Leading Scientific Schools, by the Russian Ministry of Education and Science through its grant for Scientific Research on High Energy Physics and under Contract No. 02.740.11.0244; the Netherlands Foundation for Research on Matter (FOM); the Israel Science Foundation; the Max Planck Institute for Physics, Munich, Germany; MEIN research grant No. 1 P03B 04529 (2005–2008), Poland; Warsaw University, Poland; the Russian Foundation for Basic Research, Grant 11-02- 91345-DFG_a; the Polish Ministry of Science and Higher Education as a scientific project No. DPN/N188/DESY/ 2009 and its grants for Scientific Research; the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT) and its grants for Scientific Research; the Korean Ministry of Education and Korea Science and Engineering Foundation; FNRS and its associated funds (IISN and FRIA) and by an Inter-University Attraction Poles Programme subsidized by the Belgian Federal Science Policy Office; the Spanish Ministry of Education and Science through funds provided by CICYT; the Natural Sciences and Engineering Research Council of Canada (NSERC); and the U.S. National Science Foundation

Abstract

We measure the Drell-Yan differential cross section [ital d][sup 2][sigma]/[ital dM] d[ital y][vert bar][sub [vert bar][ital y][vert bar][lt]1] over the mass range 11[lt][ital M][lt]150 GeV/[ital c][sup 2] using dielectron and dimuon data from [ital [bar p]p] collisions at a center-of-mass energy of [radical][ital s] =1.8 TeV. Our results show the 1/[ital M][sup 3] dependence that is expected from the naive Drell-Yan model. In comparison to the predictions of recent QCD calculations we find our data favor those parton distribution functions with the largest quark contributions in the [ital x] interval 0.006 to 0.03.

Abstract

Radiative decays of $\frac{J}{\ensuremath{\psi}}$ into ${K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$, ${K}_{S}^{0}{K}^{\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\pi}}^{\ensuremath{\mp}}$, $\ensuremath{\eta}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$, and $\ensuremath{\rho}\ensuremath{\gamma}$ have been studied in the $\ensuremath{\eta}(1430)$ mass range from the $8.6\ifmmode\times\else\texttimes\fi{}{10}^{6}\frac{J}{\ensuremath{\psi}}'\mathrm{s}$ produced in the DM2 experiment at the Orsay ${e}^{+}{e}^{\ensuremath{-}}$ storage ring (DCI). The $\ensuremath{\eta}(1430)$ is observed in both ${K}_{S}^{0}{K}^{\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\pi}}^{\ensuremath{\mp}}$ and ${K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$ channels. A three-body decay-angular analysis of the whole signal supports a ${J}^{P}={0}^{\ensuremath{-}}$ assignment. A substantial $K{K}^{*}(892)$ dynamics is present whereas the significance of the ${a}_{0}(980)\ensuremath{\pi}$ contribution cannot be evaluated. The $\ensuremath{\eta}(1430)$ is not observed in the $\ensuremath{\eta}\ensuremath{\pi}\ensuremath{\pi}$ channel which shows a peak in the $\frac{{f}_{1}(1285)}{\ensuremath{\eta}(1275)}$ mass range and a new state at 1398 MeV/${\mathit{c}}^{2}$, \ensuremath{\simeq}50 MeV/${\mathit{c}}^{2}$ wide. An ${a}_{0}(980)\ensuremath{\pi}$ intermediate-state contribution is present at least in the latter state. Finally, the low-statistics $\ensuremath{\rho}\ensuremath{\gamma}$ final state gives no evidence of $\ensuremath{\eta}(1430)$ production.

Abstract

Branching ratios of {ital J}/{psi} decays into {omega}{pi}{sup 0},{omega}{eta},{omega}{eta}{prime},{rho}{eta},{rho}{eta}{prime},{phi}{eta},{phi}{eta}{prime}, and {ital K}{sup *}(892){bar K}+charge conjugate are measured from the 8.6{times}10{sup 6} {ital J}/{psi}'s produced by the DM2 experiment at the Orsay {ital e}{sup +}{ital e}{sup {minus}} storage ring DCI. The {eta} and {eta}{prime} mesons are found consistent with a {ital q{bar q}} structure and a mixing angle {theta}{sub {ital P}}=({minus}19.1{plus minus}1.4){degree}.

Abstract

Top quark production offers the unique opportunity to search for a charged Higgs boson (H{sup {+-}}), as the contribution from t{yields}H{sup +}b{yields}{tau}{sup +}{nu}b can be large in extensions of the standard model. We use results from a search for top quark pair production by the Collider Detector at Fermilab (CDF) in the e{tau}+Ee{sub T}+jets and {mu}{tau}+Ee{sub T}+jets signatures to set an upper limit on the branching ratio of B(t{yields}H{sup +}b) in 106 pb{sup -1} of data. The upper limit is in the range 0.5 to 0.6 at 95% C.L. for H{sup +} masses in the range 60 to 160 GeV, assuming the branching ratio for H{sup +}{yields}{tau}{nu} is 100%. The {tau} lepton is detected through its 1-prong and 3-prong hadronic decays. (c) 2000 The American Physical Society.

Abstract

We present a measurement of the cross section for production of two or more jets as a function of dijet mass, based on an integrated luminosity of 86 pb{sup -1} collected with the Collider Detector at Fermilab. Our dijet mass spectrum is described within errors by next-to-leading order QCD predictions using CTEQ4HJ parton distributions, and is in good agreement with a similar measurement from the DOe experiment.

Abstract

This paper reports an updated measurement of the standard model CP violation parameter sin 2{beta} using the CDF Detector at Fermilab. The entire run I data sample of 110 pb{sup -1} of proton-antiproton collisions at {radical}(s)=1.8 TeV is used to identify a signal sample of {approx}400 B{yields}J/{psi} K{sub S}{sup 0} events, where J/{psi}{yields}{mu}{sup +}{mu}{sup -} and K{sub S}{sup 0}{yields}{pi}{sup +}{pi}{sup -}. The flavor of the neutral B meson is identified at the time of production by combining information from three tagging algorithms: a same-side tag, a jet-charge tag, and a soft-lepton tag. A maximum likelihood fitting method is used to determine sin 2{beta}=0.79{sub -0.44}{sup +0.41}(stat+syst). This value of sin 2{beta} is consistent with the standard model prediction, based upon existing measurements, of a large positive CP-violating asymmetry in this decay mode.

Abstract

The oscillation frequency {delta}m{sub d} of B{sup 0}B(bar sign){sup 0} mixing is measured using the partially reconstructed semileptonic decay B(bar sign){sup 0}{yields}l{sup -}{nu}(bar sign)D{sup *+}X. The data sample was collected with the CDF detector at the Fermilab Tevatron collider during 1992-1995 by triggering on the existence of two lepton candidates in an event, and corresponds to about 110 pb{sup -1} of p(bar sign)p collisions at {radical}(s)=1.8 TeV. We estimate the proper decay time of the B(bar sign){sup 0} meson from the measured decay length and reconstructed momentum of the l{sup -}D{sup *+} system. The charge of the lepton in the final state identifies the flavor of the B(bar sign){sup 0} meson at its decay. The second lepton in the event is used to infer the flavor of the B(bar sign){sup 0} meson at production. We measure the oscillation frequency to be {delta}m{sub d}=0.516{+-}0.099{sub -0.035}{sup +} {sup 0.029} ps{sup -1}, where the first uncertainty is statistical and the second is systematic.

Abstract

${B}_{d}^{0}\ensuremath{-}{B}_{d}^{0}$ oscillations are observed in ``self-tagged'' samples of partially reconstructed $B$ mesons decaying into a lepton and a charmed meson collected in $p\overline{p}$ collisions at $\sqrt{s}=1.8\mathrm{TeV}.$ A flavor tagging technique is employed which relies upon the correlation between the flavor of $B$ mesons and the charge of a nearby particle. We measure the flavor oscillation frequency to be $\ensuremath{\Delta}{m}_{d}{=0.471}_{\ensuremath{-}0.068}^{+0.078}\ifmmode\pm\else\textpm\fi{}0.034{\mathrm{ps}}^{\mathrm{\ensuremath{-}}1}.$ The tagging method is also demonstrated in exclusive samples of ${B}_{u}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{K}^{+}$ and ${B}_{d}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}{K}^{*0}(892),$ where similar flavor-charge correlations are observed. The tagging characteristics of the various samples are compared with each other, and with Monte Carlo simulations.

Abstract

We present a measurement of Z 0 boson and Drell-Yan production cross sections in pp collisions at √s =1.8TeV using a sample of 107 pb -1 accumulated by the Collider Detector at Fermilab. The Drell-Yan cross section is measured in the mass range of M μμ > 40GeV/c 2 . We compare the measurements with the predictions of quantum chromodynamics in both leading order and next-to-leading order, incorporating the recent parton distribution functions. The measurements are consistent with the standard model expectations. ©1999 The American Physical Society.

Abstract

We report the observations of the decays B{sup +}{yields}{psi}(2S)K{sup +} and B{sup 0}{yields}{psi}(2S)K*(892){sup 0} in p{ovr p} collisions at a center-of-mass energy of 1.8 TeV using a 110 pb{sup -1} data sample recorded by the Collider Detector at Fermilab. We also reconstruct the decays B{sup +}{yields}J/{psi}K{sup +} and B{sup 0}{yields}J/{psi}K*(892){sup 0} and measure the six ratios of branching fractions of these four decays. The relative branching-fraction results are shown to be consistent with phenomenological factorization calculations of hadronic B-meson decays. We use the world-average branching fraction B(B{sup +}{yields}J/{psi}K{sup +}) to derive B(B{sup +}{yields}{psi}(2S)K{sup +})=(0.56{+-}0.08{+-}0.10)x10{sup -3}, B(B{sup 0}{yields}{psi}(2S)K*(892){sup 0})=(0.92{+-}0.20{+-}0.16)x10{sup -3}, and B(B{sup 0}{yields}J/{psi}K*(892){sup 0})=(1.78{+-}0.14{+-}0.29)x10{sup -3}, where the first and second uncertainties are statistical and systematic, respectively.

Abstract

We search for new long-lived particles which decay to Z{sup 0} bosons by looking for Z{sup 0}{yields}e{sup +}e{sup -} decays with displaced vertices. We find no evidence for parent particles of the Z{sup 0} with long lifetimes in 90 pb{sup -1} of data from the CDF experiment at Fermilab. We set a cross section limit as a function of the lifetime of the parent particle for both a generic Z{sup 0} parent and a fourth-generation, charge -1/3 quark that decays into Z{sup 0}b.

Abstract

Hadronic decays of the J/\ensuremath{\psi} involving \ensuremath{\varphi} and \ensuremath{\omega} production are investigated: J/\ensuremath{\psi}\ensuremath{\rightarrow}\ensuremath{\varphi}${\ensuremath{\pi}}^{+}$${\ensuremath{\pi}}^{\mathrm{\ensuremath{-}}}$, \ensuremath{\varphi}${K}^{+}$${K}^{\mathrm{\ensuremath{-}}}$, \ensuremath{\varphi}${K}_{S}^{0}$${K}_{S}^{0}$, \ensuremath{\omega}${K}^{+}$${K}^{\mathrm{\ensuremath{-}}}$, \ensuremath{\omega}${K}_{S}^{0}$${K}_{S}^{0}$, \ensuremath{\varphi}${K}^{\mathrm{*}}$K\ifmmode\bar\else\textasciimacron\fi{}, \ensuremath{\varphi}pp\ifmmode\bar\else\textasciimacron\fi{}. Except \ensuremath{\varphi}${K}^{\mathrm{*}}$K\ifmmode\bar\else\textasciimacron\fi{} and \ensuremath{\varphi}pp\ifmmode\bar\else\textasciimacron\fi{}, these three-body final states are dominated by quasi-two-body productions. A detailed study of the ${f}_{0}$(975) production is presented. The analysis shows evidence for the ${f}_{2}$(1720) being associated to both \ensuremath{\omega} and \ensuremath{\varphi}. An upper limit is given for the \ensuremath{\varphi}\ensuremath{\eta}(1440) branching ratio.

Abstract

The Jpsi..--> gamma pi../sup +/..pi../sup -/..pi../sup +/..pi../sup -/ and J/psi..--> gamma pi../sup +/..pi../sup -/..pi../sup 0/..pi../sup 0/ decays have been studied by the DM2 experiment from 8.6 x 10/sup 6/ J/psi's. Both decays exhibit a large pseudoscalar rhorho dynamics. Three J/sup P//sup C/ = 0/sup -+/ resonant states (more than 3500 events, globally) decaying into rho/sup 0/rho/sup 0/ and with less statistical significance into rho/sup +/rho/sup -/ are observed. Their branching ratios into rho/sup 0/rho/sup 0/ and rho/sup +/rho/sup -/ support an I/sup G/ = 0/sup +/ assignment. These states, named eta(1500), eta(1800), and eta(2100), are not associated with well-established resonances.
