Quark cluster model study of isospin-2 dibaryons
- Grupo de Fisica Nuclear, Universidad de Salamanca, E-37008 Salamanca (Spain)
Based on a quark cluster model for the nonstrange sector that reproduces reasonably well the nucleon-nucleon system and the excitation of the {Delta} isobar, we generate a nucleon-{Delta} interaction and present the predictions for the several isospin-2 channels. The only attractive channels are 0{sup +} and 0{sup {minus}}, 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.
