摘要: The NΔ and ΔΔ dibaryon resonances are studied by calculating the NN scattering phase shifts with explicitly coupling these dibaryon channels in a multichannel coupling calculation with two quark models. These quark models, the chiral quark model and quark delocalization color screening model, describe the NN S, Dwave phase shifts below the π production threshold quantitatively well. Both quark models predict the 1D2 resonance discovered in NN partial wave phase shift analysis and the J=1 or 3 isoscalar resonance recently reported by CELSIUSWASA Collaboration are NΔ5S2 and ΔΔ7S3 resonance, respectively. Further measurements at COSY, LEPS and Lanzhou Cooling Storage Ring(CSR) to check the ΔΔ resonance are discussed.
