DOWNLOAD EBOOKThe QCD corrections to W production associated with a jet are studied using the ratio of W + 1 Jet to W + 0 Jets cross sections for a jet with a transverse energy of 25 GeV. The measured ratio of $0.096\pm0.005\sp{stat}\pm0.008\sp{syst}$ is significantly higher than the theoretical predictions of Giele et al. of 0.053. This discrepancy is at least partly due to the relatively unconstrained gluon distribution of the proton.
