Abstract

We present our preliminary results for semileptonic form factors of D mesons in unquenched lattice QCD. Simulations are carried out with n_f = 2 + 1 dynamical quarks using gauge configurations generated by the MILC collaboration. For the valence quarks, we adopt an improved staggered light quark action and the clover heavy quark action. Our results for D → K and D → π form factors at q² = 0 are in agreement with the experimental values.
