Abstract

The inclusion of SU(3) symmetry breaking in the

PVV

vertices and the use of the "simplest" Hamiltonian consistent with

Δ I = \frac{1}{2}

for nonleptonic

Δ S = 1

transitions bring the calculation of

{K_{2}}^{0} \to γ γ

decay mode in agreement with experiment, vis-à-vis the disagreement of two orders of magnitude previously reported.
