摘要：We report on our calculation of pion and kaon form factors in three-flavor QCD using the overlap quark action. Gauge ensembles are generated on a 163×48 lattice at a lattice spacing of 0.11 fm with pionmasses down to 310MeV. Connected and disconnectedmeson correaltors are calculated using the all-to-all quark propagator. We present our preliminary analysis on the chiral behavior of the electromagnetic and scalar form factors as well as a comparison of the shape of the K !p form factors with experiment.
