Three-body resonances in two-meson-one-baryon systems

We report four Σ's and three Λ's, in the 1500 - 1800 MeV region, as two meson - one baryon S-wave (1/2)+ 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 T-matrix have been found very close to the existing S = -1, JP=1/2+ low lying baryon resonances. The input two-body t-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.
