Rapidity correlations between high p(sub T) intermediate vector bosons and jets in (bar p)p collisions at (radical)s = 1.8 TeV

摘要

D(O) has used W (yields) e(nu) and Z (yields) e(sup +)e(sup -) events produced in association with a high p(sub T), jet to examine the effects of strong radiative corrections. We have compared the primary jet pseudorapidity distribution, as a function of reconstructed W or Z boson rapidity to leading order (LO) and Next-to-Leading order (NLO) QCD Monte Carlo generators, as well as a model based on extended color dipoles. We find that the primary jet is more central than either LO or NLO expectations. None of the Monte Carlo programs does a good job of predicting the shape of the jet distributions as a function of intermediate vector bosons rapidity.
