Abstract

We have studied the ππN system and coupled channels by using of the Faddeev equations and two N* and one Δ states, all of them with J P = 1/2 + , have been found in the formalism as dynamically generated states. In addition, signatures for a new N* resonance with J P = 1/2 + are found around an energy of 1920 MeV in the three-body center of mass system.
