Abstract
The first measurement that relates semileptonic and hadronic decay rates of the meson is performed using proton-proton collision data corresponding to of integrated luminosity collected with the LHCb detector. The measured value of the ratio of branching fractions, , is at the lower end of available theoretical predictions.
