Research Abstract

The chiral symmetry of Quantum Chromodynamics (QCD) plays an important role in the dynamics of quarks. In lattice QCD simulations, with which model independent computation of QCD is possible, only recently an exact chiral symmetry has become possible to simulate. In this study, we have performed a large scale numerical simulation of lattice QCD with 2+1 flavors which corresponds to u, d, and s quarks. We have computed various matrix elements in flavor physics which are important for tests of the standard model of elementary particle physics.
