Measurement of the ratio of branching fractions $\mathscr{B} (B^0 \to D^{*-} \tau^+ \nu_\tau) / \mathscr{B} (B^0 \to D^{*-} \mu^+ \nu_\mu)$ with hadronic $\tau$ three-prong decays
A measurement of the ratio of semileptonic branching fractions $\mathscr{B} (D^{*-}) \equiv \mathscr{B} (B^0 \to D^{*-} \tau^+ \nu_\tau) / \mathscr{B} (B^0 \to D^{*-} \mu^+ \nu_\mu)$ is performed using a data sample of proton-proton collisions, corresponding to an integrated luminosity of 3 fb$^{-1}...
