abstract
Several theoretical groups describe the antikaon-nucleon interaction at low energies within approaches based on the chiral SU(3) dynamics and including next-to-leading order contributions. We present a comparative analysis of the pertinent models and discuss in detail their pole contents. It is demonstrated that the approaches lead to very different predictions for the $K^{-}p$ amplitude extrapolated to subthreshold energies as well as for the $K^{-}n$ amplitude. The origin of the poles generated by the models is traced to the so-called zero coupling limit, in which the inter-channel couplings are switched off. This provides new insights into the pole contents of the various approaches. In particular, different concepts of forming the $\Lambda(1405)$ resonance are revealed and constraints related to the appearance of such poles in a given approach are discussed.

Absolute X-ray yields measured for kaonic copper and fluorine transitions using CZT detectors at DAΦNE, with observed suppression of the 4→3 yield in fluorine yielding a lower limit on strong-interaction width.
Hadronic molecules serve as a framework for certain exotic heavy-quark states where nonrelativistic effective field theories enable predictions with controlled uncertainty.
