Production of Bc+ 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 Bc+ → 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.

Abstract

Production of Bc+ 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 Bc+ → 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.
