Description

We perform a sensitivity study of an un-binned angular analysis of the $B\to D^{\ast }\ell {\nu }_{\ell }$ decay, including the contributions from the right-handed current. We show that the angular observable can constrain very strongly the right-handed current without the intervention of the yet unsolved $V_{cb}$ puzzle.
