Abstract
The B[subscript s][superscript 0] differential production cross section is measured as functions of the transverse momentum and rapidity in pp collisions at √s=7 TeV, using the B[subscript s][superscript 0] →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[superscript -1]. The B[subscript s][superscript 0] is reconstructed from the decays J/ψ→μ[superscript +]μ[superscript -] and ϕ→K[superscript +]K[superscript -]. The integrated B[subscript s][superscript 0] cross section times B[subscript s][superscript 0] →J/ψϕ branching fraction in the range 8
