N2 - We have analyzed the semileptonic decays B→ Dℓv and B→ D(∗) ℓv on the full suite of MILC (2+1)-flavor asqtad ensembles with lattice spacings as small as 0.045 fm and light-to-strangequark mass ratios as low as 1/20. We use the Fermilab interpretation of the clover action for heavy valence quarks and the asqtad action for light valence quarks. We compute the hadronic form factors for B→D at both zero and nonzero recoil and for B→D(∗) at zero recoil. We report our results for (Vcb).
