New physics searches via angular distributions of B ¯ → D ∗ → Dπ τ → ℓ ν τ ν ¯ ℓ ν ¯ τ $$ \overline{B}\to {D}^{\ast}\left(\to D\pi \right)\tau \left(\to \ell {\nu}_{\tau }{\overline{\nu}}_{\ell}\right){\overline{\nu}}_{\tau } $$ decays
Abstract The study of B ¯ → D ∗ τ ν ¯ τ $$ \overline{B}\to {D}^{\ast}\tau {\overline{\nu}}_{\tau } $$ angular distribution can be used to obtain information about new physics (or beyond the Standard Model) couplings, which are motivated by various B anomalies. However, the inability to measure preci...
