• 論文の詳細を見る

• A dibaryon-pole search in the complex-energy plane has been performed for J^P=2^+ and 3^- states by the three-channel (pp, NΔ, πd) K-matrix simulation of the pp-pp, pp-πd and πd-πd amplitudes of the phaseshift analyses. We have found resonance poles in the mass region of NN(2170) for 2^+ and of NN(2250) for 3^-. The average mass and width of the solutions are 2162 MeV and 48 MeV for 2^+ and 2166 MeV and 133 MeV for 3^-. Small pp elasticities (<lism>0.02 for 2^+ and 0.04<lism>for 3^-) are suggested.
