Abstract

We report the status of an ongoing lattice-QCD calculation of form factors for exclusive semileptonic decays of B mesons with both charged currents (B → πν, Bs → Kν) and neutral currents (B → π+−, B → K+−). The results are important for constraining or revealing physics beyond the Standard Model. This work uses MILC’s (2+1+1)-flavor ensembles with the HISQ action for the sea and light valence quarks and the clover action in the Fermilab interpretation for the b quark. Simulations are carried out at three lattice spacings down to 0.088 fm, with both physical and unphysical seaquark masses. We present preliminary results for correlation-function fits.
