We present the first unquenched lattice-QCD calculation of the hadronic form factors for the exclusive decay B¯→Dℓν¯ at nonzero recoil. We carry out numerical simulations on 14 ensembles of gauge-field configurations generated with 2+1 flavors of …
We calculate form-factor ratios between the semileptonic decays barB-textgreaterDtextasciicircum+elltextasciicircum-barnu and barB_s-textgreaterD_stextasciicircum+elltextasciicircum-barnu with lattice QCD. These ratios are a key theoretical input in …
