Abstract

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