Measurement of the ratio of branching fractions $\mathcal{B}(B^0 \to D^{*-}\tau^{+}\nu_\tau)/\mathcal{B}(B^0 \to D^{*-}\mu^{+}\nu_\mu)$ with $\tau$ three-prong decays

The prospects of a measurement of the branching fraction ratio $\mathcal{R}(D^*) \equiv \mathcal{B}(B^0 \to D^{*−} \tau^+ \nu_{\tau})/ \mathcal{B}(B^0 \to D^{*−} \mu^+ \nu_{\mu})$ is performed by using a data sample, corresponding to $3 \text{fb}^{−1}$ integrated luminosity, collected by LHCb at cen...
