Comment on the application of current algebra and the bag model toK→2πdecays

It is shown that applying current algebra and partial conservation of the axial-vector current to the real part instead of the magnitude of the $K\to 2\pi$ matrix element yields an enhancement factor equal to the secant of the final-state $\pi \pi$ scattering phase shift. This enhancement factor increases the ratio of $K_1^0\to 2{\pi }^0$ to $\Lambda \to n{\pi }^0$ matrix elements calculated by Katz and Tatur in the MIT bag model to 1178 MeV which is to be compared with the experimental ratio of 1142 MeV.
