  • 1. Joint Inst. for Nuclear Research, Dubna (Russian Federation)

Description

The decays ω → 3π, φ → 3π, η → π+π-γ, and KL → π+π-γ via the quark loops of anomalous type are described within the Nambu-Jona-Lasino model, based on the SU(3)LxSU(3)RxU(1)V symmetry of QCD. The importance of nondiagonal π-a1 (a1 is an axial-vector a1(1260)-mesons) transitions at legs of box quark diagrams and role of form factors of intermediate ρ-mesons in pole-type diagrams are shown
