Abstract

A sensitivity study of the unbinned angular analysis of the BD(Dπ)νB\to D^*(D\pi)\ell \nu_\ell decay is presented. In the analysis, it is shown that the Wilson coefficient of the right-handed vector current, CVRC_{V_R}, can be measured to precision of 2-4%\% using either the full set of normalised angular observables or the forward-backward asymmetry AFBA_{FB} of the charged lepton in 10 ww bins. Such angular measurements are independent of the VcbV_{cb} puzzle.
