2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/231263We discuss the hadronic molecule issue in the light and heavy meson sector. Thereby we use the radiative decays of the scalars f0(980) and a0(980) to study its possible molecular K barK structure. Further on we extend our formalism to mesons with open charm and strangeness, Ds0*(2317) and Ds1(2460), whose hadronic molecule interpretation is analyzed in weak decays with f0(980) in the final state.Talk given at 18th International Conference on Particles and Nuclei (PANIC 08), Eilat, Israel, 9-14 Nov 2008High Energy Physics - Phenomenologytext
