摘要：

The ratio of the number of W + 1 jet to W + 0 jet events is measured with the D0 detector using data from the 1992-93 Tevatron Collider run. For the W --> ev channel with a minimum jet E(T) cutoff of 25 GeV, the experimental ratio is 0.065 +/- 0.O03(stat) +/- 0.007(syst). Next-to-leading order QCD predictions for various parton distributions agree well with each other and are all over 1 standard deviation below the measurement. Varying the strong coupling constant alpha(s) in both the parton distributions and the partonic cross sections simultaneously does not remove this discrepancy.
