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. © 1999 The American Physical Society.

Abstract:

We report the results of a study of color coherence effects in pp collisions based on data collected by the DØ detector during the 1994-1995 run of the Fermilab Tevatron Collider, at a center of mass energy √s = 1.8 TeV. Initial-to-final state color interference effects are observed by examining particle distribution patterns in events with a W boson and at least one jet. The data are compared to Monte Carlo simulations with different color coherence implementations and to an analytic modified-leading-logarithm perturbative calculation based on the local parton-hadron duality hypothesis. © 1999 Published by Elsevier Science B.V.

Abstract:

We have made a precise measurement of the central inclusive jet cross section at √s = 1.8 TeV. The measurement is based on an integrated luminosity of 92pb-1 collected at the Fermilab Tevatron p̄p Collider with the D0 detector. The cross section, reported as a function of jet transverse energy (ET ≥ 60 GeV) in the pseudorapidity interval |±| ≤ 0.5, is in good agreement with predictions from next-to-leading order quantum chromodynamics. © 1999 The American Physical Society.

Abstract:

We present a measurement of the Drell-Yan cross section at high dielectron invariant mass using 120 pb^-1 of data collected in pp collisions at √ s = 1.8 TeV by the D0 Collaboration during 1992-1996. No deviation from standard model expectations is observed. We use the data to set limits on the quark-electron compositeness scale. The 95% confidence level lower limits on the compositeness scale vary between 3.3 and 6.1 TeV depending on the assumed form of the effective contact interaction. © 1999 The American Physical Society.

Abstract:

We present a measurement of t¯t production in p¯p collisions at √s = 1.8TeV from 110pb-1 of data collected in the all-jets decay channel with the D0 detector at Fermilab. A neural network analysis yields a cross section of 7.1 ± 2.8(stat) ± 1.5(syst)pb at a top quark mass (mt) of 172.1GeV/c2. Using previous D0 measurements from dilepton and single lepton channels, the combined D0 result for the t¯t production cross section is 5.9 ± 1.2(stat) ± 1.1(syst)pb for mt = 172.1GeV/c2. © 1999 The American Physical Society.
