Abstract

The first measurement that relates semileptonic and hadronic decay rates of the B⁺_c meson is performed using proton-proton collision data corresponding to 1.0 fb^-1 of integrated luminosity collected with the LHCb detector. The measured value of the ratio of branching fractions, B(B⁺_c→J/ψπ⁺)/ B(B⁺_c→J/ψμ⁺ν_μ)=0.0469±0.0028(stat)±0.0046(syst), is at the lower end of available theoretical predictions.
