Study of the strong coupling constant using W+jet processes

Creators

Description

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→eν channel with a minimum jet ET cutoff of 25 GeV, the experimental ratio is 0.065±0.003(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 αs in both the parton distributions and the partonic cross sections simultaneously does not remove this discrepancy. copyright 1995 The American Physical Society
