Phenomenology analysis of $$\bar{B}^* \rightarrow V \tau ^-\bar{\nu }_{\tau }$$ B ¯ ∗ → V τ - ν ¯ τ decays in and beyond the Standard Model

Abstract Motivated by the persistent anomalies reported in the $$b\rightarrow c \tau \bar{\nu }$$ b → c τ ν ¯ data, we investigate the semileptonic decays $$\bar{B}^* \rightarrow V \tau ^-\bar{\nu }_{\tau } (V=D^*_{u,d,s},J/\psi )$$ B ¯ ∗ → V τ - ν ¯ τ ( V = D u , d , s ∗ , J / ψ ) , within the Stan...
