Event Type: Seminar/Symposium
 

Tension currently exists between the Standard Model and experimental data for B~mesons. We present a lattice-QCD calculation of form factors for exclusive semileptonic decays of B~mesons with both charged currents and neutral currents. The results are important for constraining or revealing physics beyond the Standard Model. This work uses MILC's new (2+1+1)-flavor ensembles with physical sea-quark masses. We present preliminary results for correlation-function fits.
