We use chirally motivated effective meson-baryon potentials to describe the
low energy KˉN data including the characteristics of kaonic hydrogen.
Our results are examined in comparison with other approaches based on the
unitarity and dispersion relation for the inverse of the T-matrix. We
demonstrate that the movements of the poles generated by the model upon varying
the model parameters can serve as a tool to get additional insights on the
dynamics of the strongly coupled πΣ-KˉN system.Comment: contribution to the Chiral10 workshop, Valencia (Spain), June 21-24,
