Abstract

We present progress on an ongoing calculation of the BsDs()lνB_s\to D_s^{(*)} l \nu form factors calculated on the nf=2+1+1n_f=2+1+1 MILC ensembles and using the Highly Improved Staggered Quark action for all valence quarks. We perform the calculation at a range of bb quark masses (and lattice spacings) so that we can extrapolate to the physical bb-quark mass.
