A NN→NN∗(1440) transition potential, based on an effective quark-quark interaction and a constituent quark cluster model for baryons, is derived in the Born-Oppenheimer approach. The potential shows significant differences with respect to those obtained by a direct scaling of the nucleon-nucleon interaction. From its asymptotic behavior we extract the values of πNN∗(1440) and σNN∗(1440) coupling constants in a particular coupling scheme. | |
