Description
It is shown, that the energy dependence of the chiral based K¯N potentials, responsible for the occurrence of two poles in the I=0 sector, is the consequence of applying the on-shell factorization introduced in Oset and Ramos (Nucl Phys A 635:99, 1998). When the dynamical equation is solved without this approximation, the T-matrix has only one pole in the energy region of the Λ(1405) resonance. (author)
