Recent developments in chiral dynamics of hadrons and hadrons in nuclei

Abstract

In this talk I present recent developments in the field of hadronic physics and hadrons in the nuclear medium. I review the unitary chiral approach to meson baryon interaction and address the topics of the two dynamically generated $\Lambda (1405)$ resonances, with experiments testing it, the $\Lambda (1520)$ and $\Delta (1700)$ resonances, plus the $\Lambda (1520)$, $\Sigma (1385)$ and $\omega$ in the nuclear medium.
