Abstract:
The ratio of the W + ≥ 1 jet cross section to the inclusive W cross section is measured using W±→ e±v events from p¯p collisions at √ = 1.8 TeV. The data are from 108pb−1 of integrated luminosity collected with the Collider Detector at Fermilab. Measurements of the cross section ratio for jet transverse energy thresholds(EminT) ranging from 15 to 95 GeV are compared to theoretical predictions using next-to-leading-order QCD calculations. Data and theory agree well for EminT > 25 GeV, where the predictions lie within 1 standard deviation of the measured values. © 1998 The American Physical Society.
