Description
We present our (HPQCD) latest lattice QCD calculation of the scalar and the vector form factors for the D → Klν semi-leptonic decay over a full range of q^2 including q^2 = 0. This calculation has been performed on the N_f=2+1+1 MILC HISQ ensembles with the physical and heavier than physical light quark masses.This calculation allows us to precisely determine the central CKM matrix element, V_{cs} in the Standard Model, by comparing the lattice QCD results for the form factors and the experimental decay rate.
