Abstract:

Non-strange dibaryon resonance with the quantum numbers J^P=2^- and I=1 has been searched for in the dibaryon mass region by the three-channel (pp, NΔ, πd) K-matrix analytic continuation method using the pp-pp, pp-πd and πd-πd amplitudes obtained by the partial-wave analysis. The results suggest a resonance pole with m_R=2145∼2165 MeV, Γ_t=30∼80 MeV and a small pp width (1∼3 MeV).
