Characteristics of W production are well described by a parton-shower approximation, based solely on the qq-bar..-->..Wg subprocess with a low-p/sub T/ cutoff chosen to reproduce the total cross section through order ..alpha../sub s/. We apply this approach to QQ-bar production from the 2..-->..3-parton subprocesses in pp-bar collisions. The results agree with CERN dimuon events for a B/sup 0/-B /sup 0/ mixing parameter epsilon > or approx. = 0.1, which is at the e/sup +/e/sup -/ experimental limit and larger than standard-model expectations.
