Abstract: A bstractPolarization measurements in B¯→D∗τν¯$$ \overline{B}\to {D}^{\left(\ast \right)}\tau \overline{\nu} $$ are useful to check consistency in new physics explanations for the RD and RD*$$ {R}_{D^{*}} $$ anomalies. In this paper, we investigate the D* and… read more here.

Abstract: The measurements of $R_{K^{(*)}}=\mathcal B(B\to K^{(*)}\mu^{+}\mu^{-})/\mathcal B(B\to K^{(*)}e^{+}e^{-})$ in recent years have hinted lepton flavor non-universality and thus drawn widespread attentions. If these anomalies are induced by new physics (NP), deviations from the SM predictions… read more here.
