摘要：

A calculation for ppBAR --> W+X --> e+ nu-X in the next-to-leading-logarithm approximation is presented, utilizing a combination of analytic and Monte Carlo integration techniques. The flexibility of the Monte Carlo technique allows us to present predictions for a variety of observables, while incorporating the effects of experimental cuts. In particular, we present O(a(s)) predictions for the p(T)(e), transverse-mass, and lepton asymmetry distributions for W --> e+ nu events, including the effect of experimental cuts. We also show that the K factor for W-boson production is dependent upon the precise experimental cuts one uses to obtain an event sample.
