Naslov: pi N -> eta N data demand the existence of N(1710) P11 resonance reducing the 1700 MeV continuum ambiguity
Izvornik: Physical Review Letters (0031-9007) 97 (2006); 062002/1-4
Vrsta rada: članak
Ključne riječi: nucleon resonances; P11(1710); continuum ambiguity
Sažetak:
In spite of prolonged polemics, the agreement on the existence of N(1710) P11 resonance has not until now been reached, and 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 N(1710) P11 state, and that it presumably stays "hidden" within the continuum ambiguity of any typical single channel partial wave analyses. Consequently, its Particle Data Group confidence rating should be raised to a 4-star resonance.
