On the origin and movement of the poles in the coupled channels model
for $\bar{K}N$ interactions    [PDF]

Ales Cieply, Jaroslav Smejkal

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.
