Description
We present a lattice QCD calculation of both scalar and vector form factors associated with the D→Klν semileptonic decay over full range of $q^2$. We extract 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 rates. This calculation has been performed on the $N_f=2+1+1$ MILC HISQ ensembles including the ones with the physical light quark masses.
