We calculate the form factors for the semileptonic decays Bs → Kℓv and B → Kℓℓ with lattice QCD. We work at several lattice spacings and a range of light quark masses, using the MILC 2+1-flavor asqtad ensembles. We use the Fermilab method for the b quark. We obtain chiralcontinuum extrapolations for EK up to ∼ 1:2 GeV and then extend to the entire kinematic range with the model-independent z expansion.
