Abstract:

The DO detector is used to study pp collisions at the 1800 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 DO detector at the two pp center-of-mass energies in the transverse energy and pseudorapidity range ET>8 GeV and |η|<3.

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.
