Abstract

We discuss in this talk aspects of \bar{K}N plus coupled channels dynamics with special emphasis on the \Lambda(1405) resonance and isovector resonances in the same energy region. We comment on several experimental reactions giving rise to \pi\Sigma distributions with important implications on the spectroscopy. We also discuss recent theoretical models based con NLO SU(3) unitarized chiral perturbation theory.
