Evidence of color coherence effects in W + jets events from pp-bar collisions at s~(1/2) = 1.8 TeV

摘要

We report the results of a study of color coherence effects in pp-bar collisions based on data collected by the DO detector during the 1994-1995 run of the Fermilab Tevatron Collider, at a center of mass energy s~(1/2) = 1.8 TeV. Initial-to-final state 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.
