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/ψπ⁺ and B⁺→J/ψK⁺ decays is measured as a function of transverse momentum and rapidity in the regions 0<p_T<20GeV/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.
