Description
We present a study of the chiral behavior of light meson
form factors in QCD with three flavors of overlap quarks.
Gauge ensembles are generated at single lattice spacing 0.12fm
with pion masses down to 300 MeV. The pion and kaon
electro-magnetic form factors and the kaon semileptonic
form factors are precisely calculated using the all-to-all
quark propagator. We discuss their chiral behavior
using the NNLO chiral perturbation theory.
