Evidence of color coherence effects in W + jets events from pp collisions at √s = 1.8 TeV
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics 464:1-2 (1999) 145-155
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.

Physical Review Letters 83:15 (1999) 2896-2901
Abstract:
We report on a search for second generation leptoquarks (LQ) produced in pp collisions at √ = 1.8TeV using the D0 detector at Fermilab. Second generation leptoquarks are assumed to be produced in pairs and to decay to either μ or v and either a strange or a charm quark (q). Limits are placed on σ (pp → LQLQ → μ v + jets) as a function of the mass of the leptoquark. For equal branching ratios to μq and vq second generation scalar leptoquarks with a mass below 160 GeV/c2 vector leptoquarks with anomalous minimal vector couplings with a mass below 240 GeV/c2 and vector leptoquarks with Yang-Mills couplings with a mass below 290 GeV/c2 are excluded at the 95% confidence level. © 1999 The American Physical Society.Studies of WW and WZ production and limits on anomalous WWγ and WWZ couplings
