Abstract:

The suppression of the decay amplitude for K⁰_S →2 π in the (3,3)⊕(3,3) model of chiral symmetry breaking is examined. Pole model calculations show that the suppression factor is not ε² as Dashen stated. It is pointed out that the number of emerging pseudoscalar Goldstone bosons is less than eight, and that degenerate perturbation calculations become meaningless in this case.
