Abstract
We use a nonlocal nucleon-Δ interaction, based on a quark cluster model for the nonstrange sector, to analyze the possible existence of a resonance in the JP=0- channel with isospin 2. The employed quark cluster model has been successfully applied to the one and two nonstrange baryon properties. The nonlocal potential results to be attractive enough to generate a resonance although with a mass and width larger than the experimental predictions. There is a strong correlation between the mass and the width of the resonance due to the proximity of the nucleon-Δ threshold.
