First measurement of the b-Jet cross section in events with a W boson in pp [over-bar] collisions at [sqrt] s= 1.96 TeV (original) (raw)
2010, Physical review letters
The cross section for jets from b quarks produced with a W boson has been measured in p" p collision data from 1: 9 fb À1 of integrated luminosity recorded by the CDF II detector at the Tevatron. The W þ 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 Æ 0: 27ðstatÞ Æ 0: 42ðsystÞ pb in association with a single flavor of leptonic W boson decay over a limited kinematic phase space. This measured result cannot be ...
