Vector meson mass in the chiral symmetry restored vacuum

We calculate the mass of vector meson in chiral symmetry restored vacuum. This is accomplished by separating four quark operators appearing and axial sum rules into symmetric breaking parts depending on contribution fermion zero modes. then identify each part from fit to masses. By taking be while keeping operator vacuum value, we find that between 550 600 MeV. demonstrates breaking, responsible for difference partner, accounts only a small fraction mass.
