Dynamically generated hadronic states in the K̅N and ηN coupled-channels interactions

We compare and review the theoretical predictions for the K̅N and ηN elastic amplitudes where sizable variations are found among the considered approaches, especially at subthreshold energies relevant for studies of kaonic atoms and meson-nuclear quasi-bound states. Conditions for an appearance of dynamically generated states in meson-baryon multi-channel interactions are established and discussed for the K̅N and ηN systems.
