摘要：

We construct event generators for ppBAR --> W+X --> e+ vX and ppBAR --> Z0X --> e+e-X including complete O(alpha(s)) corrections, and interface with initial- and final-state parton showers. Problems with negative weights and double-counting multiple-parton emissions are averted. We calculate the q(T)(W) spectrum at both square-root s = 0.63 TeV and square-root s = 1.8 TeV, and compare with data and other theoretical predictions. We also present cross sections for the various W or Z plus multijet event topologies and compare with matrix-element results. We show several distributions associated with W + multijet events and find the jet rapidity distribution can be used to test the validity of our approach.
