e + e − → KK γ at the φ resonance Original Research Article

We study the K0k0γ and K+K−γ production in a φ factory. We analyze the interference between the f0(975) and a0(980) mesons with special emphasis on possible correlations of these effects in the neutral and charged channels. We take into account the initial state radiation and the necessary cuts to eliminate most of the radiation arising from the particles in the initial and final states. Implications for the study of backgrounds in the study of CP violation are also discussed.
