Lepton-flavour non-universality of $\bar{B}\to D^{\ast }\ell \bar{\nu }$ angular distributions in and beyond the Standard Model

Christoph Bobeth, Marzia Bordone, Nico Gubernari +2

We analyze in detail the angular distributions in $\bar{B}\to D^{\ast }\ell \bar{\nu }$ decays, with a focus on lepton-flavour non-universality. We investigate the minimal number of angular o…
