Abstract

We discuss a possible interpretation of the f0(980) and a0(980) mesons as hadronic molecules - a bound state of K and KÌ" mesons. Using a phenomenological Lagrangian approach we calculate the strong f0(980)→ππ and a0(980)→πη as well as the electromagnetic f0(980)→γγ and a0(980)→γγ decays. The covariant and gauge invariant model, which also allows for finite size effects of the hadronic molecule, delivers results in good agreement with available data and results of other theoretical approaches.
