On the Origin and Movement of the Poles in the Coupled Channels Model for Interactions
Abstract
The origin of the poles generated by chiral coupled-channel dynamics and applied to interactions is related to the nonzero diagonal couplings in the πΣ, and KΞ channels. An evolution of the poles from the zero coupling limit and from a limit of restored SU(3) symmetry is discussed.
