Resumen

We calculate the two-and three-body spectra of deltas using a chiral quark cluster model and a meson-exchange model for the ΔΔ interaction. The ordering of the states is pretty much model independent. Both models predict the existence of four ΔΔ bound states that couple to the NN system. Three of these states can be identified with known NN states. The fourth state corresponds to a new NN resonance with isospin 0, spin 3 and positive parity. A possible signal of this resonance appears in recent analyses of NN data.
