Production of scalar K(K)over-bar molecules in phi radiative decays

The potentialities of the production of the scalar <K(K)over bar> molecules in phi radiative decays are considered beyond the narrow resonance width approximation. It is shown that B(phi --> gamma f(0)(a(0)) --> gamma pi pi(pi eta)) approximate to (1 - 2) x 10(-5), B(phi --> gamma(f(0) + a(0)) --> gamma K+K-) less than or similar to 10(-6), and B(phi --> gamma(f(0) + a(0)) --> gamma KSKS) < 5 x 10(-8). The mass spectra in the pi pi, pi eta, K+K- channels are calculated. The imaginary part of the amplitude phi --> gamma f(0)(a(0)) is calculated analytically. The phase of the scalar resonance production amplitude that causes the interference patterns in the reaction e(+)e(-) --> gamma pi(+)pi(-) in the phi meson mass region is obtained.
