Description
We present new results on semileptonic decays of D-mesons using the highly improved staggered quark (HISQ) action for both valence and 2+1+1 sea quarks. Our calculation uses lattice spacings ranging from 0.12 fm down to 0.042 fm, including several ensembles with physical-mass pions. The focus on the talk will be on the vector and scalar form factors ($f_+$ and $f_0$) for the decays $D\to\pi$, $D\to K$ and $D_s \to K$. Phenomenological applications will be discussed.
