Dynamical Hadrons

Abstract

In this talk I briefly review the theory of resonances dynamically generated from hadron-hadron scattering, sometimes referred to as "molecules"S. I give some classical examples of meson-meson and meson-baryon systems, as well as a few examples of different approaches to describe the interaction between hadrons. To conclude, I comment on a few recent works that suggest that some of the five new narrow ${\Omega }_c$ states, recently discovered by the LHCb collaboration, can be interpreted as meson-baryon molecules.
