$B\to D^{(\ast )}$ decays from $N_f=2+1+1$ highly improved staggered quarks and clover $b$-quark in the Fermilab interpretation

Pietro Butti, Carleton DeTar, Aida El-Khadra +9

We present an update on the analysis of semileptonic $B\to D^{(\ast )}$ decays at non-zero recoil. Our computation employs $2+1+1$ FNAL-MILC ensembles with highly improved…
