A microscopic NN to NN*(1440) potential

Abstract

By means of a NN to NN*(1440) transition potential derived in a parameter-free way from a quark-model based NN potential, we determine simultaneously the $\pi N{N}^{\ast }(1440)$ and $\sigma N{N}^{\ast }(1440)$ coupling constants. We also present a study of the target Roper excitation diagram contributing to the $p(d,d^{\prime })$ reaction.
