We give an updated study on meson-baryon scattering within the framework of unitary chiral perturbation theory. We focus on S-wave scattering with strangeness -1 channel. After fixing the unknown couplings through fitting to experimental data, we then analyze the baryon spectroscopy and the sub-threshold behavior of the [Formula: see text] amplitude. We end with a summary and a brief outlook.
