The B(s)β†’D(s)lΞ½B_{(s)} \to D_{(s)}l\nu Decay with Highly Improved Staggered Quarks and NRQCD

Abstract

We report on progress of a lattice QCD calculation of the B→DlνB\to Dl\nu and Bs→DslνB_s\to D_s l\nu 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.Comment: Presented at Lattice 2017, the 35th International Symposium on Lattice Field Theory at Granada, Spain (18-24 June 2017
