$Bto D^astell u$ at non-zero recoil

We present preliminary blinded results from our analysis of the form factors for $Brightarrow D^astell u$ decay at non-zero recoil. Our analysis includes 15 MILC asqtad ensembles with $N_f=2+1$ flavors of sea quarks and lattice spacings ranging from $aapprox 0.15$ fm down to $0.045$ fm. The valence light quarks employ the asqtad action, whereas the $b$ and $c$ quarks are treated using the Fermilab action. We discuss the impact that our results will have on $left|V_{cb}right|$ and $R(D^ast)$.
