Research Abstract

The latest lattice QCD calculations are progressing with steadily increasing accuracy due to the rapid development of the computer and the numerical algorithm. Fully dynamical QCD simulations with two degenerate light (up and down) and heavier (strange) flavors of quarks have been mostly devoted to studies of the hadron structure by the worldwide lattice QCD community during the past several years. In this study, we take advantage of 2+1 flavor dynamical QCD gauge configurations, which are publicly available to lattice QCD community through ILDG (International Lattice Data Grid) and then study the nucleon structure and also hadron properties from the viewpoint of the SU(3) flavor symmetry breaking by first-principles calculation in a model-independent way.
