Measurements of the differential production cross sections dσ/dpBT and dσ/dyB for B⁰ mesons produced in pp collisions at √s=7 TeV are presented. The data set used was collected by the CMS experiment at the LHC and corresponds to an integrated luminosity of 40 pb⁻¹. The production cross section is measured from B⁰ meson decays reconstructed in the exclusive final state J/ψK0S, with the subsequent decays J/ψ→μ⁺μ⁻ and K0S→π⁺π⁻. The total cross section for pBT>5 GeV and |yB|<2.2 is measured to be 33.2±2.5±3.5 μb, where the first uncertainty is statistical and the second is systematic.
