Dijet mass spectrum and a search for quark compositeness in (p)p collisions at sqrt(s) = 1.8 TeV
Physical Review Letters 82:12 (1999) 2457-2462
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.Evidence of color coherence effects in W + jets events from pp collisions at √s = 1.8 TeV

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.
