Abstract

I identify a new realization of chiral SU(3)×SU(3) symmetry which, in a sense, encompasses both the Wigner-Weyl mode and the Nambu-Goldstone mode. The chiral symmetry is unbroken, but there are Goldstone bosons. Furthermore, the light vector mesons, as well as the pseudoscalar mesons, are intimately involved because the chiral partners of the pseudoscalars are the longitudinal components of the vectors. I discuss the connection of this realization with vector dominance, the Kawarabayashi-Suzuki-Riazuddin-Fayyazuddin relation, and the large-N approximation.
