Abstract

Recent theoretical studies of the e⁺e^- → K⁺K^-γ process are described. Three main reaction mechanisms are considered: the initial state radiation, the final state radiation and the strong interaction between the outgoing K⁺K^- mesons. The K⁺K^- effective mass distributions are derived for three different models which in past have been used for a description of the e⁺e^- → π⁺π^-η data. Also the numerical results for the angular photon and kaon distributions are presented. A new model of the e⁺e^- → M₁M₂γ reactions is outlined which can serve for multichannel analyses of the radiative processes with a production of two pseudoscalar mesons M₁ and M₂.
