Research Abstract

We performed large-scale simulations of lattice QCD with exact chiral symmetry for a precise determination of the hadronic matrix elements needed for the precise test of the Standard Model. The reliability of the numerical simulations was demonstrated by carefully examining the consistency of our results for the pion electromagnetic form factor with chiral perturbation theory. We then precisely determine the nucleon strange quark content and the kaon semileptonic form factors which are important for the direct experimental searches for dark matter and precise determination of the CKM matrix elements.
