A THREE-CHANNEL (pp, NƊ, πd) K-MATRIX ANALYSIS OF THE DIBARYON RESONANCES
Résumé
A dibaryon-pole search in the complex energy plane has been performed for Jp = 2+ and 3- states in terms of the three channel (pp, NƊ, πd) K-matrix simulation of the pp-pp, pp-πd and πd-πd amplitudes of the phaseshift analysis. We have found the resonance poles in the mass region of NN(2170) for 2+ and of NN(2250) for 3-. One remarkable finding is small pp elasticities (≤ for 2+ and ≤ 0.04 for 3-).
