Order-${\alpha }_s$ corrections to observables from $p\overline{p}\to W^{+}X\to e^{+}\nu X$

A calculation for $p\overline{p}\to W^{+}X\to e^{+}\nu X$ 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 $O\left({\alpha }_s\right)$ predictions for the $p_T\mathrm{}\left(e\right)\mathrm{}$, transverse-mass, and lepton asymmetry distributions for $W\to e^{+}\nu$ 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.
