摘要：

We have performed a calculation for the three-body Delta rho IEuro system by using the fixed center approximation to Faddeev equations, taking the interaction between Delta and rho, Delta and pi, and rho and 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, 3/2 and J (P) = 1/2(+), 3/2(+) and 5/2(+) baryon states.
