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