Abstract

The cross section for jets from b quarks produced with a W boson has been measured in p (p) over bar collision data from 1.9 fb(-1) of integrated luminosity recorded by the CDF II detector at the Tevatron. The W + b-jets process poses a significant background in measurements of top quark production and prominent searches for the Higgs boson. We measure a b-jet cross section of (2.74+/-0.27(stat)+/-0.42(syst)) pb in association with a single flavor of leptonic W boson decay over a limited kinematic phase space. This measured result cannot be accommodated in several available theoretical predictions.
