The leptonic decays of charged \(\mathrm{B}\) mesons belong to the golden decay-channels at \(\mathrm{B}\) factories. The expected branching fractions in the Standard Model of particle physics (SM) are small, hence leptonic decays are so-called rare-decays. The theoretical uncertainties on the predicted branching fraction are small and the possible influence of physics beyond the Standard Model (BSM) can be large.
