Description
In spite of long-lasting discussions, the agreement on the existence of the N(1710) P11 resonance has not yet been reached, so the Particle Data Group declares it as a 3-star resonance only. We show that the proper inclusion of inelastic channels in the coupled-channel formalism indisputably demands the existence of the N(1710) P11 state, and that it presumably stays hidden within the continuum ambiguity of a typical single-channel partial-wave analysis. Consequently, the Particle Data Group confidence rating of this state should be raised to a 4-star resonance
