The cross section for jets from b quarks produced with a W boson has been measured in p-pbar 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.

Abstract
The cross section for jets from b quarks produced with a W boson has been measured in p-pbar 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.File in questo prodotto:
