Abstract
It is shown, that the energy dependence of the chiral based potentials, responsible for the occurrence of two poles in the sector, is the consequence of applying the on-shell factorization introduced in [E. Oset, A. Ramos, Nucl. Phys. A 635(1998)99]. When the dynamical equation is solved without this approximation, the -matrix has only one pole in the energy region of the resonance.
