Measurement of the B⁺ production cross section in pp collisions at vs=7TeV

Abstract: Measurements of the total and differential cross sections d=dpBT and d=dyB for Bþ mesons produced in pp collisions at ffiffi s p ¼ 7 TeV are presented. The data correspond to an integrated luminosity of 5:8 pb1 collected by the CMS experiment operating at the LHC. The exclusive decay Bþ ! J=c Kþ, with J=c ! þ, is used to detect Bþ mesons and to measure the production cross section as a function of pBT and yB. The total cross section for pB T > 5 GeV and jyBj < 2:4 is measured to be 28:1 2:4 2:0 3:1 b, where the first uncertainty is statistical, the second is systematic, and the last is from the luminosity measurement
