The enigmatic $\Delta (1600)$ resonance

Abstract

Our recently proposed model of the $\Delta (1600)$ resonance, in which the dominant component is a quasi-bound state of the $\Delta (1232)$ and the pion, is confronted with a similar model of the $N^{\ast }(1440)$ resonance as its counterpart in the P11 partial wave. We stress an essentially different mechanism responsible for generating the two resonances.
