Quark cluster model study of isospin-2 dibaryons

Based on a quark cluster model for the nonstrange sector that reproduces reasonably well the nucleon-nucleon system and the excitation of the isobar, we generate a nucleon- interaction and present the predictions for the several isospin-2 channels. The only attractive channels are 0+ and 0-, but not attractive enough to generate a resonance. If a resonance is artificially generated and is required to have the observed experimental mass, then our model predicts a width that agrees with the experimental result.
