Abstract
We report four 's and three 's, in the 1500 - 1800 MeV region, as two meson - one baryon S-wave resonances. We solve Faddeev equations in the coupled channel approach. The invariant mass of one of the meson-baryon pairs and that of the three particles have been varied and peaks in the squared three body -matrix have been found very close to the existing = -1, low lying baryon resonances. The input two-body -matrices for meson-meson and meson-baryon interaction have been calculated by solving the Bethe-Salpeter equation with the potentials obtained in the chiral unitary approach.
