Abstract

We make use of a NN → NN∗ (1440) transition potential derived from a quark model in a parameter-free way, to study the Roper excitation diagram contributing to the reaction p(d, d ′ ). We also determine the πNN∗ (1440) and σNN∗ (1440) coupling constants.

Keywords

Roper excitation diagram; πNN∗ (1440) and σNN∗ (1440) coupling constants
