1. Formation of compressed flat electron beams with high transverse-emittance ratios

Author: J. Zhu, P. Piot, D. Mihalcea, and C. R. Prokop
Subjects: Nuclear and particle physics. Atomic energy. Radioactivity, QC770-798
Abstract: Flat beams—beams with asymmetric transverse emittances—have important applications in novel light-source concepts and advanced-acceleration schemes and could possibly alleviate the need for damping rings in lepton colliders. Over the last decade, a flat beam generation technique based on the conversion of an angular-momentum-dominated beam was proposed and experimentally tested. In this paper we explore the production of compressed flat beams. We especially investigate and optimize the flat beam transformation for beams with substantial fractional energy spread. We use as a simulation example the photoinjector of Fermilab’s Advanced Superconducting Test Accelerator. The optimizations of the flat beam generation and compression at Advanced Superconducting Test Accelerator were done via start-to-end numerical simulations for bunch charges of 3.2 nC, 1.0 nC, and 20 pC at ∼37 MeV. The optimized emittances of flat beams with different bunch charges were found to be 0.25 μm (emittance ratio is ∼400), 0.13 μm, 15 nm before compression, and 0.41 μm, 0.20 μm, 16 nm after full compression, respectively, with peak currents as high as 5.5 kA for a 3.2-nC flat beam. These parameters are consistent with requirements needed to excite wakefields in asymmetric dielectric-lined waveguides or produce significant photon flux using small-gap micro-undulators.

2. Three-dimensional analysis of wakefields generated by flat electron beams in planar dielectric-loaded structures

Author: D. Mihalcea, P. Piot, and P. Stoltz
Subjects: Nuclear and particle physics. Atomic energy. Radioactivity, QC770-798
Abstract: An electron bunch passing through a dielectric-lined waveguide generates Čerenkov radiation that can result in a high-peak axial electric field suitable for acceleration of a subsequent bunch. Axial fields beyond gigavolt-per-meter are attainable in structures with sub-mm sizes depending on the achievement of suitable electron bunch parameters. A promising configuration consists of using a planar dielectric structure driven by flat electron bunches. In this paper we present a three-dimensional analysis of wakefields produced by flat beams in planar dielectric structures thereby extending the work of Tremaine, Rosenzweig, and Schoessow, Phys. Rev. E 56, 7204 (1997)PLEEE81063-651X10.1103/PhysRevE.56.7204] on the topic. We especially provide closed-form expressions for the normal frequencies and field amplitudes of the excited modes and benchmark these analytical results with finite-difference time-domain particle-in-cell numerical simulations. Finally, we implement a semianalytical algorithm into a popular particle-tracking program thereby enabling start-to-end high-fidelity modeling of linear accelerators based on dielectric-lined planar waveguides.

3. Comparison of experimental tests and theory for a rectangular two-channel dielectric wakefield accelerator structure

Author: S. V. Shchelkunov, T. C. Marshall, G. Sotnikov, J. L. Hirshfield, Wei Gai, M. Conde, J. Power, D. Mihalcea, and Z. Yusof
Subjects: Nuclear and particle physics. Atomic energy. Radioactivity, QC770-798
Abstract: Experimental results are reported for test beam acceleration and deflection in a two-channel, cm-scale, rectangular dielectric-lined wakefield accelerator structure energized by a 14-MeV drive beam. The dominant waveguide mode of the structure is at ∼30 GHz, and the structure is configured to exhibit a high transformer ratio (∼12∶1). Accelerated bunches in the narrow secondary channel of the structure are continuously energized via Cherenkov radiation that is emitted by a drive bunch moving in the wider primary channel. Observed energy gains and losses, transverse deflections, and changes in the test bunch charge distribution compare favorably with predictions of theory.

4. Longitudinal electron bunch diagnostics using coherent transition radiation

Author: D. Mihalcea, C. L. Bohn, U. Happek, and P. Piot
Subjects: Nuclear and particle physics. Atomic energy. Radioactivity, QC770-798
Abstract: The longitudinal charge distribution of electron bunches in the Fermilab/NICADD photoinjector was determined using the coherent transition radiation produced by electrons passing through a thin metallic foil. The autocorrelation of the transition radiation signal was measured with a Michelson-type interferometer. The response function of the interferometer was determined from measured and simulated intensity spectra for low electron bunch charge and maximum longitudinal compression. Both pyroelectric and Golay detectors were used for these measurements. A Kramers-Kronig technique was used to determine longitudinal charge distribution. Measurements were performed for electron bunch lengths in the range from 0.3 to 2 ps (rms). To test the accuracy of this interferometric method, the longitudinal charge distribution was measured for double-peaked electron bunches with known distance between the two pulses. The agreement between measured bunch length and simulation is within 30%.

5. Experimental investigation of the longitudinal beam dynamics in a photoinjector using a two-macroparticle bunch

Author: P. Piot, R. Tikhoplav, D. Mihalcea, and N. Barov
Subjects: Nuclear and particle physics. Atomic energy. Radioactivity, QC770-798
Abstract: We have developed a two-macroparticle bunch to explore the longitudinal beam dynamics through various components of the Fermilab/NICADD photoinjector. Such a two-macroparticle bunch is generated by splitting the ultraviolet pulse from the photocathode drive laser. The presented method allows the exploration of radio-frequency-induced compression in the 1.625 cell radio frequency gun and the booster cavity. It also allows a direct measurement of the momentum compaction of the magnetic bunch compressor. The measurements are compared with analytical and numerical models.

Abstract: Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): Grant TE 137/2020 Background. Patients with heart failure and reduced ejection fraction (HFrEF) are at high risk for death. So far, left ventricular ejection fraction (LVEF) measured by 2-dimensional echocardiography (2DE) has been considered the main predictor of mortality in HFrEF. However, there are new echo parameters reflecting cardiac remodeling, assessed by 3-dimensional echocardiography (3DE), that might improve risk stratification in HFrEF. Aim. To assess comparative prognostic value of left heart function and remodeling parameters, measured by 2DE versus 3DE, in patients with HFrEF. Methods. 142 consecutive patients (60 ± 17 years, 91 males), diagnosed with HFrEF, in sinus rhythm, were assessed by 2DE, using dedicated views for the LV and left atrium (LA), and by 3DE, with full-volume multi-beat acquisitions of the LV and LA. Left ventricular volumes (LVVs) were measured from 2DE views, using the modified Simpson biplane method, and from 3DE using dedicated software. Maximal and minimal indexed LAVs were measured from 2DE, using the biplane area-length formula (2D_LAVmax and 2D_LAVmin); and from 3DE, using dedicated software package (3D_LAVmax and 3D_LAVmin). Patients were followed for 5 years (57 ± 11 months) after the index event. Primary outcome was mortality. Secondary outcomes were a composite endpoint (CE) of death and hospitalization for heart failure (HHF); HHF; and a composite cardiac events end-point (MACE) of death, HHF, myocardial infarction, coronary revascularization, arrhythmias, or cardiac resynchronization therapy. Results. At 5 years we recorded 52 deaths, 70 CE, 36 HHF, and 73 MACE. At baseline, mean 2DE and 3DE LVEFs were 32 ± 10% and 32 ± 9%, respectively. There was no significant difference between the LVVs or LVEF by 2DE or 3DE between survivors and non-survivors. However, there was a significant difference for total and indexed 2D_LAVmax, 3D_LAVmax, and 3D_LAVmin (Table 1) between survivors and non-survivors. Similarly, there was no significant correlations with endpoints for the 2DE or 3DE LVVs. However, total and indexed 2D_LAVmax correlated with death, CE, HFH, and MACE, all with P In a linear multivariate regression model, that included 2DE and 3DE LVEF, indexed 2D and 3D LAV max and min, only indexed 3D_LAVmin was an independent predictor for death (p Furthermore, by ROC analysis, an indexed LAV of 30 ml/m2 by 3DE was able to predict death ( Sb 94%, Sp 80%, AUC 0.70), CE (Sb 98%, Sp 80%, AUC 0.67), HFH (Sb 96%, Sp 80%, 0.67), and MACE (Sb 93%, Sp 76%, AUC 0.66). Conclusion. LVEF by 2DE and 3DE, while smaller in non-survivors, was unable to predict death in a small cohort of patients with HFrEF. However, LAVs, particularly by 3DE, were able to predict cardiac events, suggesting the potential key value of evolving cardiac substrate. Abstract Table 1

Abstract: Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): Grant TE 137/2020 Background. In primary mitral regurgitation (PMR) left ventricular (LV) remodeling is an adaptive process with prognostic significance. Aim. To characterize LV deformation parameters related to PMR severity for a better understanding of LV pathophysiology, in patients with mild to severe PMR and preserved LV ejection fraction (EF). Methods. 48 patients (56 ± 14 years, 42% men) with PMR (mild - 12 patients, moderate - 12 patients, severe - 24 patients) and 50 age and sex matched-controls (56 ± 12 years, 48% men) were analyzed by 2-dimensional speckle-tracking echocardiography (2D STE) for LV endo, mid, and epicardial longitudinal strain (LS); endo, mid, and epicardial circumferential strain (CS); and radial strain (RS). LV volumes and EF, and LA volumes and emptying fraction (EmF) were measured by 3D echocardiography. MR severity was quantified by vena contracta (VC), PISA radius, MR regurgitant volume, and EROA measurements, according to the 2021 ESC guidelines. Results. 3D LVEF had no significant difference between PMR patients and controls (p= 0.11). From control subjects to mild, moderate, and severe PMR, there was a progressive reduction of LS and RS (Figures 1 and 2), but not of CS. By 2D STE multilayer analysis, when compared to controls, PMR patients had decreased endo-, mid-, and epi-LS (p Conclusion. When compared to normal subjects, patients with PMR and preserved LVEF have altered LV longitudinal and radial deformation, with preserved circumferential strain. All longitudinal layers and all LV segments were similarly affected. Only longitudinal strain correlates with MR severity and atrial function. Our study suggests that a comprehensive evaluation of the LV deformation should be included in the assessment of patients with PMR, in order to identify early stages of LV dysfunction, starting even from mild MR.

Abstract: RCHOP chemotherapy (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) in non-Hodgkin's lymphoma (NHL) has a high risk of cardiotoxicity, with increased morbidity and mortality. Aim To define new parameters, such as 3D LV deformation, arterial stiffness and biomarkers able to detect late cardiotoxicity. Methods 54 patients (26 men, 57±10 years) with NHL, scheduled to receive RCHOP, with LVEF>50%, were assessed at baseline, after the 4th cycle of RCHOP and 2 years after completion of therapy. Assessment included 3D echocardiography for LV EF and deformation - longitudinal, radial, circumferential, area strain (LS, RS, CS, AS), Arteriograph for pulse wave velocity (PWV) and biomarkers (troponin I, NT-pro-BNP). Cardiotoxicity was defined as a decrease of LVEF 10% from the baseline value. Results 11 patients (group I) developed cardiotoxicity, while 43 patients did not (group II) (LVEF decreased from 59±3 to 56±2 vs 58±3 to 47±2, p Conclusion Assessment of 3D myocardial deformation, arterial stiffness and biomarkers is able to detect late cardiovascular toxicity, and to predict further decline of LVEF in patients with NHL.

Abstract: Electron-cooling offers a relatively simple scheme to enable high-luminosity collisions in future electron-ion and hadron colliders. Contemplated TeV-energy hadron colliders require relativistic (sub 100 MeV) high-charge [${\cal O}(\mbox{nC})$] electron beams with a specific transverse eigenemittance partition. This paper discusses the generation of high-charge ($Q\le 3.2$~nC) 40 MeV electron bunches with eigenemittance partition consistent with requirements associated with electron-cooling option for future electron-ion colliders. The supporting experiment was performed at the FAST facility at FermiLab. The data are compared with numerical simulations and the results discussed in the context of beam requirement for future electron-ion colliders., Comment: 8 pages, 9 figures

Abstract: High-repetition-rate sources of bright electron bunches have a wide range of applications. They can directly be employed as probes in electron-scattering setups, or serve as a backbone for the generation of radiation over a broad range of the electromagnetic spectrum. This paper describes the development of a compact sub-Mega-electronvolt (sub-MeV) electron-source setup capable of operating at MHz repetition rates and forming sub-picosecond electron bunches with transverse emittance below 20 nm. The setup relies on a conduction-cooled superconducting single-cell resonator with its geometry altered to enhance the field at the surface of the emitter. The system is designed to accommodate cooling using a 2 W pulse-tube cryogen-free cryocooler operated at 4.2 K. Although we focus on the case of a photoemitted electron bunch, the scheme could be adapted to other emission mechanisms.

Abstract: The ability to engineer cathodes at the nano-scale have opened new possibilities such as enhancing quantum efficiency via surface-plasmon excitation, forming ultra-low-emittance beams, or producing structured electron beams. In this paper, we present numerical investigations of the beam dynamics associated with this class of cathode in the weak- and strong-field regimes. We finally discuss the possible applications of some of the achievable cathode patterns when coupled with other phase space manipulations.

Abstract: The intensity and the brilliance of the compact X-ray sources based on channeling radiation are strongly dependant on the electron beam quality. It was recently proposed to combine a field-emission electron source with channeling radiation through a diamond crystal to produce high-spectral-brilliance X-rays. There are two experiments in preparation at Fermilab to prove this technique. The beam energy in the two cases are 5-MeV and 40-MeV respectively. The field-emitted beams have emittance in the nanometer range when the microbunch is 25 ps long and the charge is about 2.5fC. RF guns operating at 1.3 GHz can produce trains of at least 2 × 105 microbunches. In this contribution we present beam-dymamics simulations of a the field-emission and subsequent accelerator up to the channeling-radiation target.

Abstract: We plan to use very small emittance electron beams created from our novel, single tip cathodes to make a channeling-radiation X-ray source for X-ray imaging, especially phase contrast imaging. We calculate that we can preserve the electron emittance from the source to the crystal, and focus to a 40 nm spot on the crystal face for 40 MeV electrons. This yields an X-ray source with good coherence properties. We discuss our plan for experiments at Fermilab with 4.5 MeV electrons at the High Brightness Electron Source Laboratory, and with 40 MeV electrons at the Advanced Superconducting Test Accelerator. We also present the state of our art with cathode construction and testing. Electrons come from the cathodes by field-emission, with the electric field enhanced by geometric properties of a very small, robust diamond tip. This can create an electron beam with very small emittance. We estimate that the normalized emittance of such a beam at the cathode is 3 nm rad. We currently test the cathodes in DC, high-voltage test stands. We will begin experiments placing the cathodes in RF guns in early 2013.

Abstract: The DØ experiment enjoyed a very successful data-collection run at the Fermilab Tevatron collider between 1992 and 1996. Since then, the detector has been upgraded to take advantage of improvements to the Tevatron and to enhance its physics capabilities. We describe the new elements of the detector, including the silicon microstrip tracker, central fiber tracker, solenoidal magnet, preshower detectors, forward muon detector, and forward proton detector. The uranium/liquid-argon calorimeters and central muon detector, remaining from Run I, are discussed briefly. We also present the associated electronics, triggering, and data acquisition systems, along with the design and implementation of software specific to DØ. © 2006 Elsevier B.V. All rights reserved.

Abstract: We report a measurement of the differential cross section for W boson production as a function of its transverse momentum in proton-antiproton collisions at √s = 1.8 TeV. The data were collected by the DØ experiment at the Fermilab Tevatron Collider during 1994-1995 and correspond to an integrated luminosity of 85 pb-1. The results are in good agreement with quantum chromodynamics over the entire range of transverse momentum. © 2001 Elsevier Science B.V.

Abstract: Using the DO detector, we have observed events produced in (p) over barp collisions that contain W or Z bosons in conjunction with very little energy deposition ("rapidity gaps") in large forward regions of the detector. The fraction of W boson events with a rapidity gap (a signature for diffraction) is 0.89 +/- (0.19)(0.17)% and the probability that the non-diffractive background fluctuated to yield the observed diffractive signal is 3 x 10(-14), corresponding to a significance of 7.5 sigma. The Z boson sample has a gap fraction of 1.44 +/- (0.61)(0.52)%, with a significance of 4.4 sigma. The diffractive events have very similar properties to the more common non-diffractive component.

Abstract: We examine properties of ttbar candidates events in lepton+jets final states to establish the helicities of the W bosons in t->W+b decays. Our analysis is based on a direct calculation of a probability that each event corresponds to a ttbar final state, as a function of the helicity of the W boson. We use the 125 events/pb sample of data collected by the DO experiment during Run I of the Fermilab Tevatron collider at sqrt{s}=1.8 TeV, and obtain a longitudinal helicity fraction of F_0=0.56+/-0.31, which is consistent with the prediction of F_0=0.70 from the standard model.

Abstract: We report a search for effects of large extra spatial dimensions in ppbar collisions at a center-of-mass energy of 1.8 TeV with the DZero detector, using events containing a pair of electrons or photons. The data are in good agreement with the expected background and do not exhibit evidence for large extra dimensions. We set the most restrictive lower limits to date, at the 95% confidence level, on the effective Planck scale between 1.0 TeV and 1.4 TeV for several formalisms and numbers of extra dimensions., Comment: 6 pages, 2 figures, submitted to Phys.

Abstract: In this paper, we present recent results from bunch-shaping experiments using α-BBO crystal at the High Brightness Electron Beam Source Laboratory (HBESL). α-BBO crystals were used to shape the ultra-short laser pulse ( < 100fs) at HBESL to generate twin pulses at the cathode. The twin electron pulses were transported down the linac ( < 5 MeV) to a transverse deflecting mode cavity and the temporal profile recorded on the screen. The longitudinal time profile of the twin pulses show the difference between the effect of crystals and the longitudinal space charge effect. The electron beam was recorded for various position of the crystal and bunch charge.

Abstract: Structured cathodes – cathodes with a segmented emission surface – are finding an increasing number of applications and can be combined with a variety of emission mechanisms, including photoemission and field emission. These cathodes have been used to enhance the quantum efficiency of metallic cathodes when operated as plasmonic cathodes, have produced high-current electron bunches though field emission from multiple tips, and can be used to form beams with transverse segmentations necessary for improving the performance of accelerator-based light sources. In this report we present recent progress towards the development of finite-difference time-domain particle-in-cell simulations using the emission process in structured cathodes based on the WARP framework. The simulations give further insight on the localized source of the emitted electrons which could be used for additional high-fidelity start-to-end simulations of electron accelerators that employ this type of electron source.

Abstract: SciDAC has had a major impact on computational beam dynamics and the design of particle accelerators. Particle accelerators -- which account for half of the facilities in the DOE Office of Science Facilities for the Future of Science 20 Year Outlook -- are crucial for US scientific, industrial, and economic competitiveness. Thanks to SciDAC, accelerator design calculations that were once thought impossible are now carried routinely, and new challenging and important calculations are within reach. SciDAC accelerator modeling codes are being used to get the most science out of existing facilities, to produce optimal designs for future facilities, and to explore advanced accelerator concepts that may hold the key to qualitatively new ways of accelerating charged particle beams. In this poster we present highlights from the SciDAC Accelerator Science and Technology (AST) project Beam Dynamics focus area in regard to algorithm development, software development, and applications.

Abstract: We have searched for the signature of 3- and 4-body decays of pair-produced scalar top quarks (stop) in the inclusive final state containing an electron, a muon, and significant missing transverse energy using a sample of p p events corresponding to 108.3 pb−1 of data collected with the DO detector at Fermilab. The search is done in the framework of the minimal supersymmetric standard model assuming that the neutralino ( χ 0 1 ) is the lightest supersymmetric particle and is stable. No evidence for a signal is found and we derive cross-section upper limits as a function of stop (t) and neutralino masses in different decay scenarios leading to the blν χ 0 1 final state.

Abstract: Using the D empty set detector, we have studied events produced in (p) over barp collisions that contain large forward regions with very little energy deposition ("rapidity gaps") and concurrent jet production at center-of-mass energies of roots = 630 and 1800 GeV. The fraction of events with forward or central jets associated with rapidity gaps is compared to predictions for hard diffraction. We also extract the momentum loss for scattered protons in such processes. (C) 2002 Elsevier Science B.V. All rights reserved.

Abstract: Flat beams -- beams with asymmetric transverse emittances -- have important applications in novel light-source concepts, advanced-acceleration schemes and could possibly alleviate the need for damping rings in lepton colliders. Over the last decade, a flat-beam-generation technique based on the conversion of an angular-momentum-dominated beam was proposed and experimentally tested. In this paper we explore the production of compressed flat beams. We especially investigate and optimize the flat-beam transformation for beams with substantial fractional energy spread. We use as a simulation example the photoinjector of the Fermilab's Advanced Superconducting Test Accelerator (ASTA). The optimizations of the flat beam generation and compression at ASTA were done via start-to-end numerical simulations for bunch charges of 3.2 nC, 1.0 nC and 20 pC at ~37 MeV. The optimized emittances of flat beams with different bunch charges were found to be 0.25 {\mu}m (emittance ratio is ~400), 0.13 {\mu}m, 15 nm before compression, and 0.41 {\mu}m, 0.20 {\mu}m, 16 nm after full compression, respectively with peak currents as high as 5.5 kA for a 3.2-nC flat beam. These parameters are consistent with requirements needed to excite wakefields in asymmetric dielectric-lined waveguides or produce significant photon flux using small-gap micro-undulators., Comment: 17 p

Abstract: We report on the first successful operation of a field-emitter-array cathode in a conventional L-band radio-frequency electron source. The cathode consisted of an array of $\sim 10^6$ diamond diamond tips on pyramids. Maximum current on the order of 15~mA were reached and the cathode did not show appreciable signs of fatigue after weeks of operation. The measured Fowler-Nordheim characteristics, transverse beam density, and current stability are discussed. Numerical simulations of the beam dynamics are also presented., Comment: 4 pages, 7 figures; preprint submitted to Applied Physics Letters

Abstract: We report on a measurement of the ratio of the differential cross sections for W and Z boson production as a function of transverse momentum in proton-antiproton collisions at sqrt(s) = 1.8 TeV. This measurement uses data recorded by the D0 detector at the Fermilab Tevatron in 1994-1995. It represents the first investigation of a proposal that ratios between W and Z observables can be calculated reliably using perturbative QCD, even when the individual observables are not. Using the ratio of differential cross sections reduces both experimental and theoretical uncertainties, and can therefore provide smaller overall uncertainties in the measured mass and width of the W boson than current methods used at hadron colliders., Comment: 10 pages, 2 figures, to be published in Physics Letters B

Abstract: We report results of a search for flavor-changing neutral current (FCNC), lepton flavor, and lepton-number violating decays of the ${D}^{0}$ (and its antiparticle) into three and four bodies. Using data from Fermilab charm hadroproduction experiment E791, we examine modes with two leptons (muons or electrons) and a ${\ensuremath{\rho}}^{0}$, ${\overline{K}}^{*0}$, or $\ensuremath{\varphi}$ vector meson or a nonresonant $\ensuremath{\pi}\ensuremath{\pi}$, $K\ensuremath{\pi}$, or $\mathrm{KK}$ pair of pseudoscalar mesons. No evidence for any of these decays is found. Therefore, we present branching-fraction upper limits at 90% confidence level for the 27 decay modes examined (18 new).

Abstract: We apply a quasi-model-independent strategy ("Sleuth") to search for new high p_T physics in approximately 100 pb^-1 of ppbar collisions at sqrt(s) = 1.8 TeV collected by the DZero experiment during 1992-1996 at the Fermilab Tevatron. We systematically analyze many exclusive final states and demonstrate sensitivity to a variety of models predicting new phenomena at the electroweak scale. No evidence of new high p_T physics is observed.

Abstract: We report on a study of the ratio of inclusive three-jet to inclusive two-jet production cross sections as a function of total transverse energy in p (p) over bar collisions at it center-of-mass energy roots = 1.8 TeV, using data collected with the DO detector during the 1992-1993 run of the Fermilab Tevatron Collider. The measurements are used to deduce preferred renormalization scales in perturbative O(alpha (3)(s)) QCD calculations in modeling soft-jet emission.

Abstract: We report a new measurement of the pseudorapidity (eta) and transverse-energy (Et) dependence of the inclusive jet production cross section in pbar b collisions at sqrt(s) = 1.8 TeV using 95 pb**-1 of data collected with the DZero detector at the Fermilab Tevatron. The differential cross section d^2sigma/dEt deta is presented up to |eta| = 3, significantly extending previous measurements. The results are in good overall agreement with next-to-leading order predictions from QCD and indicate a preference for certain parton distribution functions.

Abstract: From a sample of $848\ifmmode\pm\else\textpm\fi{}44$ ${D}_{s}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{+}$ decays, we find $\ensuremath{\Gamma}({D}_{s}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{+})/\ensuremath{\Gamma}({D}_{s}^{+}\ensuremath{\rightarrow}\ensuremath{\varphi}{\ensuremath{\pi}}^{+})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.245\ifmmode\pm\else\textpm\fi{}{0.028}_{\ensuremath{-}0.012}^{+0.019}$. Using a Dalitz plot analysis of this three body decay, we find significant contributions from the channels ${\ensuremath{\rho}}^{0}(770){\ensuremath{\pi}}^{+}$, ${\ensuremath{\rho}}^{0}(1450){\ensuremath{\pi}}^{+}$, ${f}_{0}(980){\ensuremath{\pi}}^{+}$, ${f}_{2}(1270){\ensuremath{\pi}}^{+}$, and ${f}_{0}(1370){\ensuremath{\pi}}^{+}$. We also present the values obtained for masses and widths of the resonances ${f}_{0}(980)$ and ${f}_{0}(1370)$.

Abstract: From a sample of 1172 +/- 61 D(+)-->pi(-)pi(+)pi(+) decays, we find gamma(D(+)-->pi(-)pi(+)pi(+))/gamma(D(+)-->K-pi(+)pi(+)) = 0.0311 +/- 0.0018(+0.0016)(-0.0026). Using a coherent amplitude analysis to fit the Dalitz plot of these decays, we find strong evidence that a scalar resonance of mass 478(+24)(-23) +/- 17 MeV/c(2) and width 324(+42)(-40) +/- 21 MeV/c(2) accounts for approximately half of all decays.

Abstract: Bottom quark production in pbar-p collisions at sqrt(s)=1.8 TeV is studied with 5 inverse picobarns of data collected in 1995 by the DO detector at the Fermilab Tevatron Collider. The differential production cross section for b jets in the central rapidity region (|y(b)| < 1) as a function of jet transverse energy is extracted from a muon-tagged jet sample. Within experimental and theoretical uncertainties, DO results are found to be higher than, but compatible with, next-to-leading-order QCD predictions.

Abstract: We present a measurement of asymmetries in the production of Λ c + and Λ c − baryons in 500 GeV/ c π − -nucleon interactions from the E791 experiment at Fermilab. The asymmetries were measured as functions of Feynman x ( x F ) and transverse momentum squared ( p T 2 ) using a sample of 1 819±62 Λ c 's observed in the decay channel Λ c + → pK − π + . We observe more Λ c + than Λ c − baryons, with an asymmetry of (12.7±3.4±1.3)% independent of x F and p T 2 in our kinematical range (−0.1⩽ x F ⩽0.6 and 0.0⩽ p T 2 ⩽8.0 (GeV/ c ) 2 ). This Λ c asymmetry measurement is the first with data in both the positive and negative x F regions.

Abstract: We present a study of correlations between D and $${\overline D}$$ mesons produced in 500 GeV/cπ−-nucleon interactions, based on data from experiment E791 at Fermilab. We have fully reconstructed 791 ± 44 charm meson pairs to study correlations between the transverse and longitudinal momenta of the two D mesons and the relative production rates for different types of D meson pairs. We see slight correlations between the longitudinal momenta of the D and the $${\bar D}$$ , and significant correlations between the azimuthal angle of the D and the $${\bar D}$$ . The experimental distributions are compared to a next-to-leading-order QCD calculation and to predictions of the PYTHIA/JETSET Monte Carlo event generator. We observe less correlation between transverse momenta and different correlations between longitudinal momenta than these models predict for the default values of the model parameters. Better agreement between data and theory might be achieved by tuning the model parameters or by adding higher order perturbative terms, thus contributing to a better understanding of charm production. The relative production rates for the four sets of charm pairs, $$D^0{{\overline D}^0}, D^0 D^{-}, D^+{{\overline D}^0}, D^+ D^{-}$$ as calculated in the PYTHIA/JETSET event generator with the default parameters, agree with data as far as the relative ordering, but predict too many $$D^+ {{\overline D}^0}$$ pairs and too few $$D^+ D^{-}$$ pairs.

Abstract: We present measurements of the b-bbar production cross section and angular correlations using the D0 detector at the Fermilab Tevatron p-pbar Collider operating at sqrt(s) = 1.8 TeV. The b quark production cross section for |y(b)| 6 GeV/c is extracted from single muon and dimuon data samples. The results agree in shape with the next-to-leading order QCD calculation of heavy flavor production but are greater than the central values of these predictions. The angular correlations between b and bbar quarks, measured from the azimuthal opening angle between their decay muons, also agree in shape with the next-to-leading order QCD prediction.

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.
