Abstract
We consider meson-baryon interactions in S-wave with strangeness ™1. This is a sector populated by plenty of resonances interacting in several two-body coupled Channels. We consider a large set of experimental data, where the recent experiments are remarkably accurate. This requires a sound theoretical description to account for all the data and we employ Unitary Chiral Perturbation Theory up to and including \( \mathcal{O} \)(p 2). The spectroscopy of our Solutions is studied within this approach, discussing the rise of the two Λ(1405)-resonances and of the Λ(1670), Λ(1800), Σ(1480), Σ(1620) and Σ(1750). We finally argue about our preferred fit.
