Dynamically generated N~* resonances from the interaction of two mesons and a baryon

摘要：

We have studied the ππN system and coupled channels by using of the Faddeev equations and two N~* and one △ 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.
