Description
In the SM, the electroweak bosons couple to the three lepton families with the same strength having the only difference in their behaviour due to the difference in mass. The current measurements of the ratios of branching fractions for b-hadrons decaying into final states with different lepton flavours deviate of the order of 3 σ with respect to the Standar Model. This talk presents recent results of lepton flavour universality tests in b→cℓν decays, using hadronic or muonic τ decays, performed at LHCb.
Other results regarding charged-current decays of b-hadrons will also be presented.
