We compute the form factors for the $B\ensuremath{\rightarrow}K{l}^{+}{l}^{\ensuremath{-}}$ semileptonic decay process in lattice QCD using gauge-field ensembles with $2+1$ flavors of sea quark, generated by the MILC Collaboration. The ensembles span

The rare decay B→πℓ^{+}ℓ^{-} arises from b→d flavor-changing neutral currents and could be sensitive to physics beyond the standard model. Here, we present the first ab initio QCD calculation of the B→π tensor form factor f_{T}. Together

We present the first unquenched lattice-QCD calculation of the hadronic form factors for the exclusive decay $\overline{B}\ensuremath{\rightarrow}D\ensuremath{\ell}\overline{\ensuremath{\nu}}$ at nonzero recoil. We carry out numerical simulations on

We calculate the kaon semileptonic form factor f+(0) from lattice QCD, working, for the first time, at the physical light-quark masses. We use gauge configurations generated by the MILC Collaboration with Nf = 2 + 1 + 1 flavors of sea quarks, which i
