Abstract: We use chirally motivated effective meson-baryon potentials to describe the low energy (K) over barN 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 pi Sigma-(K) over barN system.
Keywords: chiral Lagrangians; coupled channels; meson-baryon interactions
