Heavy-light meson semileptonic decays with staggered light quarks
Description
We report on exploratory studies of heavy-light meson semileptonic decays using AsqTad light quarks, NRQCD heavy quarks and Symanzik improved glue on coarse quenched lattices. Oscillatory contributions to three-point correlators coming from the staggered light quarks are found to be handled well by Bayesian fitting methods. B meson decays to both the Goldstone pion and to one of the point-split non-Goldstone pions are investigated. One-loop perturbative matching of NRQCD/AsqTad heavy-light currents is incorporated
