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.9 p.application/pdfengcc by (c) CERN; LHCb Collaboration, 2015http://creativecommons.org/licenses/by/3.0/es/Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article6536862019-05-09info:eu-repo/semantics/openAccess
