1+1+1 flavor QCD plus QED simulation at the physical point

We present the results of 1 + 1 + 1 flavor QCD + QED simulation at the physical point, in which the dynamical quark effects in QED and the up-down quark mass difference are incorporated by the reweighting technique. The physical quark masses together with the lattice spacing are determined with m(pi+), m(K+), m(K0) and m(Omega-) as physical inputs. Calculations are carried out using a set of 2 + 1 flavor QCD configurations near the physical point generated by the nonperturbatively O(a)-improved Wilson quark action and the Iwasaki gauge action at beta = 1.9 on a 32(3) x 64 lattice. We evaluate the values of the up, down and strange quark masses individually with nonperturbative QCD renormalization.
