Nonlocal calculation for nonstrange dibaryons and tribaryons

Abstract

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 $NN$, $N\Delta$, and $\Delta \Delta$, while the three-body systems are $NNN$, $NN\Delta$, $N\Delta \Delta$, and $\Delta \Delta \Delta$. We use as input the nonlocal $NN$, $N\Delta$, and $\Delta \Delta$ 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.
