Abstract
The B_s^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_s^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^(-1). The B_s^0 is reconstructed from the decays J/ψ → μ^+μ^- and ϕ → K^+K^-. The integrated B_s^0 cross section times B_s^0 → J/ψϕ branching fraction in the range 8 < p_T^B < 50 GeV/c and |y^B| < 2.4 is measured to be 6.9±0.6±0.6 nb, where the first uncertainty is statistical and the second is systematic.
