  • Within the formalism and theoretical framework of asymptotic SUF(4) symmetry plus the constraint algebras involving the generators of the underlying symmetries of QCD, we derive an important relation between meson isoscalar-isovector matrix elements of the electromagnetic current and corresponding matrix elements of the axial-vector charge A. A lower bound is calculated for the rate which indicates that is of the order of 1 MeV, with its exact value depending upon the rates and. The estimate of the lower bound is independent of the specific quark and glue content of the. © 1987 The American Physical Society.
