Test of lepton flavour universality using hadronic tau decays with the LHCb detector
The goal of this internship was to realize a preliminary study on the measurement of the $R$($D$$^{∗}$) parameter, defined as the ratio between the two branching fractions${\cal{R}}(D^{*-})\equiv {\cal{B}}(B^0 \to D^{*-} \tau^+ \nu_{\tau})/{\cal{B}}(B^0 \to D^{*-} \mu^+\nu_{\mu})$, using the τ$^{...
