Bound states of [Formula Presented] and [Formula Presented] systems

We study possible bound states of the [Formula Presented] and [Formula Presented] systems by using a two-body interaction derived from the chiral quark cluster model. The systems of two and three deltas, which will appear in nature as dibaryon and tribaryon resonances with zero strangeness, have large similarities with the corresponding two- and three-nucleon systems. The two deepest bound [Formula Presented] states are those with angular momentum and isospin [Formula Presented] and [Formula Presented] which have the same quantum numbers as the [Formula Presented]-[Formula Presented] (deuteron) and [Formula Presented] (virtual) [Formula Presented] states. Similarly, the more strongly bound [Formula Presented] state is that with angular momentum and isospin [Formula Presented] which has precisely the same quantum numbers as the triton.
