W-Jet Rapidity Correlations in $p\bar{p}$ Collisions at $\sqrt{s}=1.8$ TeV

Abstract

D0 has used W -> e nu events produced in association with a high $p_T$ jet to examine the effects of strong radiative corrections. We have compared the primary jet pseudorapidity distribution, as a function of reconstructed W rapidity to leading order (LO) and next to leading order (NLO) QCD Monte Carlos, as well as a model based on extended color dipoles. Our preliminary analysis finds that the primary jet is more central than either LO or NLO expectations and is in qualitative agreement with the color dipole model.
