Lepton universality violation and right-handed currents in b→cτν
We consider the recent LHCb result for Bc→J/ψτν in conjunction with the existing anomalies in R(D) and R(D⋆) within the framework of a right-handed current with enhanced couplings to the third generation. The model predicts a linear relation between the observables and their SM values in terms of tw...
