Abstract:	摘要： AbstractThe inclusive b-jet production cross section in pp collisions at a center-of mass energy of 7 TeV is measured using data collected by the CMS experiment at the LHC. The cross section is presented as a function of the jet transverse momentum in the range 18 < pT < 200 GeV for several rapidity intervals. The results are also given as the ratio of the b-jet production cross section to the inclusive jet production cross section. The measurement is performed with two different analyses, which differ in their trigger selection and b-jet identification: a jet analysis that selects events with a b jet using a sample corresponding to an integrated luminosity of 34 pb−1, and a muon analysis requiring abjetwithamuonbasedonanintegratedluminosityof3pb−1. Inbothapproachestheb jets are identified by requiring a secondary vertex. The results from the two methods are in agreement with each other and with next-to-leading order calculations, as well as with predictions based on the pythia event generator. 出版者： Springer Science and Business Media LLC 出版日期： 2012-04 出處： Journal of High Energy Physics, 2012-04, Vol.2012 (4), p.084-, Article 84 資源來源： Publicly available content database 識別號： ISSN: 1029-8479 識別號： ISSN: 1126-6708 識別號： ISSN: 1127-2236 識別號： EISSN: 1029-8479 識別號： DOI: 10.1007/jhep04(2012)084
