| Outline of Final Research Achievements |
The effect of isospin symmetry breaking was ignored in traditional lattice QCD calculations because it was expected to be small compared to their statistical errors. But in recent precise numerical calculations, we can no longer ignore the effect. There are several previous attempts. They consider the effect partially or are done away the physical point.
The aim of this project is the realization of calculations at the physical point, which include the full effect of isospin symmetry breaking. We realized it and estimated the quark masses.
