Nonleptonic meson decays in the bag model

Nonleptonic meson decays are discussed in the current-current picture making use of the MIT bag model. It is shown that upon inclusion of an enhancement factor due to asymptotic freedom the decay amplitude for ${K_s}^0\to {\pi }^0{\pi }^0$ is also of the correct order of magnitude. Furthermore, we have computed the enhancement-independent ratio $\frac{a({K_s}^0\to {\pi }^0{\pi }^0)}{A\left(A_0^0\right)}$ and have found it to be equal to 833 MeV, which is to be compared with the experimental ratio of 1142 MeV. We conclude by presenting a prediction for the decay width for $D\to K^{-}{\pi }^{+}$, where $D^0$ is the lowest charmed meson.
