Δρπ Interaction Leading to N* and Δ* Resonances

摘要

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 and π, 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 J P = 1/2+, 3/2+ and 5/2+ baryon states.
