The \boldmath$B\to D^{\ast }\ell \nu$ semileptonic decay at nonzero recoil and its implications for $|V_{cb}|$ and $R(D^{\ast })$

Alejandro Vaquero Avilés-Casco, Carleton DeTar, Aida X. El-Khadra +3

We present nearly final results from our analysis of the form factors for $B\to D^{\ast }\ell \nu$ decay at nonzero recoil. Our analysis includes 15 MILC asqtad ensembles with $N_f=2+1$…
