AbstraktAbstract
We use chirally motivated effective meson-baryon potentials to describe the low energy K̅ N 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 π Σ - K̅ N system.
