| Abstract: | Production of B + c mesons in proton-proton collisions at a center-of-mass energy of 8 TeV is studied with data corresponding to an integrated luminosity of 2.0 fb − 1 recorded by the LHCb experiment. The ratio of production cross sections times branching fractions between the B + c → J / ψ π + and B + → J / ψ K + decays is measured as a function of transverse momentum and rapidity in the regions 0 < p T < 20 GeV / c and 2.0 < y < 4.5 . The ratio in this kinematic range is measured to be ( 0.683 ± 0.018 ± 0.009 ) % , where the first uncertainty is statistical and the second systematic. |
