Lepton angular asymmetries in semileptonic charmful B decays

Abstract

We study the lepton angular distributions in $B\to D^{(\ast )}\ell {\nu }_{\ell }$ decays. The lepton angular asymmetries in the decays with the general effective interactions are examined. We demonstrate that the asymmetries are sensitive to new physics with a right-handed quark current.
