Abstract

We develop a new formalism to study KK threshold phenomena with resonances f₀, a₀ and K⁺K^- atom (kaonium) included. The approach provides two possible scenarios for f₀-a₀ mixing. Drastic interference patterns can be observed in K⁺K^-electroproduction at CEBAF, pd→ ~³HeX reaction, and N N annihilation.
