Abstract

We have performed a calculation for the three body Δρπ\Delta \rho \pi system by using the fixed center approximation to Faddeev equations, taking the interaction between Δ\Delta and ρ\rho, Δ\Delta andπ\pi, and ρ\rho and π\pi from the chiral unitary approach. We find several peaks in the modulus squared of the three-body scattering amplitude, indicating the existence of resonances, which can be associated to known I=1/2,3/2I=1/2, 3/2 and JP=1/2+,3/2+J^P=1/2^+, 3/2^+ and 5/2+5/2^+ baryon states.
