Description
We study the possible existence of nonstrange dibaryons and tribaryons by solving the bound-state problem of the two- and three-body systems composed of nucleons and deltas. The two-body systems are NN, NΔ, and ΔΔ, while the three-body systems are NNN, NNΔ, NΔΔ, and ΔΔΔ. We use as input the nonlocal NN, NΔ, and ΔΔ potentials derived from the chiral quark cluster model by means of the resonating group method. We compare with previous results obtained from the local version based on the Born-Oppenheimer approximation
