Abstract

In this talk I report on the recent developments in the subject of dynamically generated resonances. In particular I discuss the γp → K⁰Σ⁺ and γn → K⁰Σ⁰ reactions, with a peculiar behavior around the K^*0Λ threshold, due to a 1/2^- resonance around 2035 MeV. Similarly, I discuss a BES experiment, decay, which provides evidence for a new h₁ resonance around 1830 MeV that was predicted from the vector–vector interaction. A short discussion is then made about recent advances in the charm and beauty sectors.

Based on a plenary talk presented at the Seventh International Symposium on Chiral Symmetry in Hadrons and Nuclei, Beijing, China, 27–30 October 2013.
