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: A bstractWe present a model to explain LHCb’s recent measurements of RK and RK∗$$ {R}_{K^{\left(\ast \right)}} $$ based on an anomaly-free, spontaneously-broken U(1)F gauge symmetry, without any fermionic fields beyond those of the Standard Model… read more here.
