Abstract We study possible bound states of the {Delta}{Delta} and {Delta}{Delta}{Delta} 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 {Delta}{Delta} states are those with angular momentum and isospin (j,i)=(1,0) and (j,i)=(0,1) which have the same quantum numbers as the {sup 3}S{sub 1}-{sup 3}D{sub 1} (deuteron) and {sup 1}S{sub 0} (virtual) NN states. Similarly, the more strongly bound {Delta}{Delta}{Delta} state is that with angular momentum and isospin (J,I)=((1)/(2),(1)/(2)) which has precisely the same quantum numbers as the triton. {copyright} {ital 1997} {ital The American Physical Society}
