description

We have performed a calculation for the three body Δρπ system by using the fixed center approximation to Faddeev equations, taking the interaction between Δ and ρ, Δ andπ, and ρ and π 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=1/2,3/2 and JP=1/2+,3/2+ and 5/2+ baryon states.
