Radiative decays with scalar mesons a(980) and f(980) in Resonance Chiral Theory
Abstract
The ϕ(1020) radiative decays form a good playground for study of the low-lying a(980) and f(980) scalar mesons. The complicated interplay of kaon loop mechanism, isoscalar meson mixing and momentum dependence of the effective couplings manifests itself in the invariant mass distributions in the ϕ(1020)→ππγ and πηγ spectra. These distributions are fitted in framework of Resonance Chiral Theory.
