摘要
The decays of a light scalar meson into a vector meson and a photon (S -> V(gamma)) are evaluated in the tetraquark and quarkonium assignments of the scalar states. A link with the radiative decays phi -> S gamma is established: experimental results for S -> V gamma will make it possible to decide if the direct, quark-loop contribution to phi -> S gamma or the kaon-loop contribution is dominant. Also strong decays S -> P P - where P denotes it pseudoscalar meson - are investigated: within our scheme, the tetraquark assignment works better than the quarkonium one.
