Measurement of the Bs0 production cross section with Bs0?J/? Decays in pp collisions at vs=7TeV

Abstract: The B0s differential production cross section is measured as functions of the transverse momentum and rapidity in pp collisions at ffiffis p ¼ 7 TeV, using the B0s ! J=c  decay, and compared with predictions based on perturbative QCD calculations at next-to-leading order. The data sample, collected by the CMS experiment at the LHC, corresponds to an integrated luminosity of 40 pb1. The B0s is reconstructed from the decays J=c ! þ and  ! KþK. The integrated B0s cross section times B0s ! J=c  branching fraction in the range 8 < pBT < 50 GeV=c and jyBj < 2:4 is measured to be 6:9 0:6 0:6 nb, where the first uncertainty is statistical and the second is systematic.
