Abstract
From a Faddeev calculation for the system we show the plausible existence of three dynamically generated baryon states below 2.3 GeV whereas only two resonances, and are cataloged in the Particle Data Book Review. Our results give theoretical support to data analyses extracting two distinctive resonances, and from which the mass of is estimated. We propose that these two resonances should be cataloged instead of This proposal gets further support from the possible assignment of the other baryon states found in the approach in the with sectors to known baryonic resonances. In particular, is naturally interpreted as a bound state.
