On the origin and movement of the poles in the coupled channels model for $\bar{K}N$ interactions
The origin of the poles generated by chiral coupled-channel dynamics and applied to $\bar{K}N$ interactions is related to the nonzero diagonal couplings in the $\pi\Sigma$, $\bar{K}N$ and $K\Xi$ channels. An evolution of the poles from the zero coupling limit and from a limit of restored SU(3) symme...

| Zusammenfassung: | The origin of the poles generated by chiral coupled-channel dynamics and
applied to $\bar{K}N$ interactions is related to the nonzero diagonal couplings
in the $\pi\Sigma$, $\bar{K}N$ and $K\Xi$ channels. An evolution of the poles
from the zero coupling limit and from a limit of restored SU(3) symmetry is
discussed. |
