    "abstract": "We study s-wave meson-baryon scattering using the chiral unitary model. We\nconsider $1/2^{-}$ baryon resonances as quasibound states of the low lying\nmesons ($\\pi,K,\\eta$) and baryons ($N,\\Lambda,\\Sigma,\\Xi$). In previous works,\nthe subtraction constants which appear in loop integrals were found to largely\ndepend on the channels, and it was necessary to fit these constants to\nreproduce the data. In order to extend this model to all channels with fewer\nparameters, we introduce flavor SU(3) breaking interactions in the framework of\nchiral perturbation theory. It is found, however, that the observed SU(3)\nbreaking in meson-baryon scattering cannot be explained by the present SU(3)\nbreaking interactions. The role and importance of the subtraction constants in\nthe present framework are discussed.",
