Unbinned Angular Analysis of $B\to D^*\ell ν_\ell$ and the Right-handed Current

In this article, we perform a sensitivity study of an unbinned angular analysis of the $B\to D^*\ell ν_\ell$ 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.
