title = "Measurement of the ratio of B-c(+) branching fractions to J/psi pi(+) and J/psi mu(+)nu(mu) final states",
abstract = "The first measurement that relates semileptonic and hadronic decay rates of the Bc+ meson is performed using proton-proton collision data corresponding to 1.0fb-1 of integrated luminosity collected with the LHCb detector. The measured value of the ratio of branching fractions, B(Bc+→J/ψπ+)/ B(Bc+→J/ψμ+νμ)=0.0469±0.0028(stat)±0.0046(syst), is at the lower end of available theoretical predictions. {\textcopyright} 2014 CERN, for the LHCb Collaboration.",
