Abstract
Measurements of the differential production cross sections dσ/dp_T^B and dσ/dy^B for B^0 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 B^0 meson decays reconstructed in the exclusive final state J/ψK_S^0, with the subsequent decays J/ψ→μ^+μ^- and K_S^0→π^+π^-. The total cross section for p_T^B>5 GeV and |y^B|<2.2 is measured to be 33.2±2.5±3.5 μb, where the first uncertainty is statistical and the second is systematic.
