The Bs0 differential production cross section is measured as functions of the transverse momentum and rapidity in pp collisions at √s=7TeV, using the Bs0→J/ψ 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 40pb -1. The Bs0 is reconstructed from the decays J/ ψ→μ+μ- and →K+K -. The integrated Bs0 cross section times Bs0→J/ψ branching fraction in the range 8 Creative Commons Attribution 3.0 License.
