The B0s differential production cross section is measured as functions of the transverse momentum and rapidity in pp collisions at √s=7 TeV, using the B0s→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 B0s is reconstructed from the decays J/ψ→μ⁺μ⁻ and Φ→K⁺K⁻. The integrated B0s cross section times B0s→J/ψΦ branching fraction in the range 8BT <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.
