Abstract
We argue that cataloged as a resonance in the Particle Data Book Review (PDG), should be interpreted instead as two distinctive resonances, and . Our argument is based on a solution of the problem in a Fixed Center Approximation (FCA) to the Fadeev equations. can then be interpreted as a bound state. As a corollary can be understood as a bound state.
