THE ISOSPIN BREAKING IN HADRON
SPECTROSCOPY AND THE LIGHT QUARK MASSES
DETERMINATION IN LATTICE QCD+QED
ABSTRACT
Recent development of the lattice simulation enables us to access hadron properties with great accuracy. In this talk, I present the study of the isospin breaking effect on hadron spectroscopy, using lattice QCD configurations generated by Nf=2 dynamical domain wall fermions, which are combined with quenched non-compact lattice QED configurations.
In particular, I will discuss the splitting of charged and neutral pseudoscalar mesons, from which we determine light quark masses using experimental pseudoscalar masses as inputs.
Everyone is welcome
