Lepton Flavour Universality tests in the decay channel $B^0 \to D^{*-} \tau^+\nu_\tau$ with $\tau^+ \to \pi^+\pi^-\pi^+\bar\nu_\tau$ at LHCb
This document reports the first measurement of $B^0 \to D^{*-} \tau^+\nu_\tau$ branching fraction performed by the LHCb Collaboration considering semileptonic b-hadron decays with the $\tau$ lepton reconstructed with three charged pions in the final state. The impact of such measurement on the curre...
