Study of the measurement of the ratio $\mathcal R(D_s^*)$ at LHCb
The semileptonic $b$ hadron decays with a heavy lepton are sensitive to non Standard Model couplings between quarks and leptons. The B-Factories and LHCb have previously performed various measurements of the observable $\mathcal R(D^{(*)})$. A global average of these measurements shows a discrepancy...
