Abstract: (Springer)
We study the isovector part of strong, electromagnetic and weak interactions in a spontaneously brokenSU2×SU2 chiral symmetry. In this framework we cannot fit the experimental data. Then, assuming [Qi5,Qj5]=−iεijkQk, we make the same study in a spontaneously brokenO3,1 chiral symmetry. The results agree quantitatively and qualitatively with phenomenology. The axial vector and scalar mesons turn out to be some sort of ghosts. We predict a massmA1≅666 MeV.- FIELD THEORY: UNIFIED INTERACTION
