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. © 2014 CERN, for the LHCb Collaboration.
