Abstract

We discuss a possible interpretation of the scalar mesons f(0)(980) and a(0)(980) as hadronic molecules - bound states of K and (K) over bar K mesons. Using a phenomenological Lagrangian approach we calculate strong as well as the electromagnetic decay properties of both scalars. The covariant and gauge invariant model, which also allows for finite size effects of the hadronic molecule, delivers results in good agreement with experimental data.
