Description

We perform a sensitivity study of an unbinned angular analysis of the $B\to D^*(D\pi)\ell\nu$ decay, including the contributions from the right-handed (R.H.) vector current. We show that the Wilson coefficient of the R.H. vector current can be strongly constrained by measuring the normalized angular observables $\langle g_i \rangle$ (i=1,2,...,11) without the intervention of the $V_{cb}$ puzzle.
