Exploring new physics in the angular distribution of $\bar{B}\to D^{\ast }(\to D\pi ){\tau }^{-}(\to V^{-}{\nu }_{\tau }){\bar{\nu }}_{\tau }$

Si-Yuan Liu, Alakabha Datta, Xian-Wei Kang

The decays $\bar{B}\to D^{\ast }{\tau }^{-}{\bar{\nu }}_{\tau }$ provide sensitive probes of new physics in the $b\to c\tau \nu$ transition. We discuss the effects of new physics in the decay cha…
