We present the first unquenched lattice-QCD calculation of the form factors for the decay B→D∗ℓν at nonzero recoil. Our analysis includes 15 MILC ensembles with Nf=2+1 flavors of asqtad sea quarks, with a strange quark mass close to its physical mass. The lattice spacings range from a≈0.15 fm down to 0.045 fm, while the ratio between the light- and...
