The $B_{(s)}\to D_{(s)}l\hat{I}½$ Decay with Highly Improved Staggered Quarks and NRQCD

Abstract

We report on progress of a lattice QCD calculation of the $B\to Dl\hat{I}½$ and $B_s\to D_{s}l\hat{I}½$ semileptonic form factors. We use a relativistic staggered action (HISQ) for light and charm quarks, and an improved non-relativistic (NRQCD) action for bottom, on the second generation MILC ensembles.
