comment Why performing axial symmetry, results in the same masses for pion and sigma mesons?
It seems that this result is general . For example for vector transformations, pions rotate in isospin space and it is written that if vector transformation is a symmetry of QCD, pion isotriplets should have the same mass. I want to know how these symmetries lead to this result. Before writing any example (Hamiltonian) the author tell this as a general result. Why?
