Chiral doublet model for the positive and negative parity nucleons
D. Jido
We discuss the properties of the nucleon (N) and its excited state with odd parity (N*) under the aspect of chiral symmetry, identifying them with suitable representations of the c…

Regulariztion dependence of S=0 and S=-1 meson-baryon system in the chiral unitary model
S. I. Nam, H. -Ch. KIm, T. Hyodo +2
We investigate the dependence of s-wave meson-baryon scattering amplitudes on different regularizations within the framework of the chiral unitary model. We employ two different re…
