The phi->K0K0gamma decay

Abstract

The scalar contributions to the radiative decay $\phi\to K^0\bar K^0\gamma$ are studied within the framework of the Linear Sigma Model. Theoretical predictions for the associated subprocesses $\phi\to f_0\gamma$ and $\phi\to a_0\gamma$ as well as the ratio $\phi\to f_0\gamma/a_0\gamma$ are also given.
