dc.description.abstractThe Bs0 differential production cross section is measured as functions of the transverse momentum and rapidity in pp collisions at √s=7  TeV, using the Bs0→J/ψϕ 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  pb-1. The Bs0 is reconstructed from the decays J/ψ→μ+μ- and ϕ→K+K-. The integrated Bs0 cross section times Bs0→J/ψϕ branching fraction in the range 8<pTB<50  GeV/c and |yB|<2.4 is measured to be 6.9±0.6±0.6  nb, where the first uncertainty is statistical and the second is systematic.es_ES
