摘要：
Using a chiral unitary model in which the negative parity nucleon resonance N* = N*(1535) is generated dynamically by means of the Bethe-Salpeter equation with coupled meson-baryon channels in the S = 0 sector, we have obtained the pi(0)N*N* and eta N*N* couplings. The eta(0)N*N* coupling has smaller strength hut the same sign as the eta(0)NN coupling. This rules out the mirror assignment of chiral symmetry where the ground state nucleon N and the negative parity resonance N* are envisaged as chiral partners in the baryon scoter.
