dc.descriptionThe decay ϕ-> f_0(980) γand process e^+e^- -> ϕf_0(980) are considered within the local Nambu-Jona-Lasinio model. In the amplitudes of these processes contributions of s-quark and kaon loops are taken into account. The kaon loop gives a dominant contribution. Our estimation for the decay width of ϕ-> f_0 γis in satisfactory agreement with recent experimental data. This allows us to make some predictions for cross sections of the process e^+e^- -> γ^* -> ϕf_0 which can be tested in the C-τfactory. The total and differential cross sections of this process are calculated and presented in the figures.
