Abstract
The decay and process are considered within the local Nambu-Jona-Lasinio model. In the amplitudes of these processes, contributions of -quark and kaon loops are taken into account. The kaon loop gives a dominant contribution. Our estimation for the decay width of is in satisfactory agreement with recent experimental data. This allows us to make some predictions for cross sections of the process which can be tested in the C- factory. The total and differential cross sections of this process are calculated and presented in the figures.
