Abstract

Strong interactions between pairs of the K⁺K⁻ and $K^{0} {\bar{K}}^{0}$ ${K^0}{\bar K^0}$ mesons can be studied in radiative decays of ϕ(1020) mesons. We present a theoretical model of the reactions $e^{+} e^{-} \to ϕ \to K^{+} K^{-} γ$ ${e^ + }{e^ - } \to \phi \to {K^ + }{K^ - }\gamma$ and $e^{+} e^{-} \to ϕ \to K^{0} {\bar{K}}^{0} γ$ ${e^ + }{e^ - } \to \phi \to {K^0}{\bar K^0}\gamma$ . The K⁺K⁻ and $K^{0} {\bar{K}}^{0}$ ${K^0}{\bar K^0}$ effective mass dependence of the differential cross sections is derived. The total cross sections and the branching fractions for the two radiative ϕ decays are calculated.
