abstract

  • We discuss an extension of the hypothesis of asymptotic level realization of SU(3) to a certain chiral SU(3) SU(3) charge-charge-density algebra, which is applied to the ground-state mesons. It produces interesting dynamical constraints for various couplings of the ground-state mesons which, among other results, permit us to compute the rate of the φ→πγ decay. This decay is forbidden in this formulation if the masses of ρ and ω are degenerate. © 1978 The American Physical Society.
