$\pi NN^*(1440)$ and $\sigma NN^*(1440)$ coupling constants from 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, we determined simultaneously the $\pi NN^*(1440)$ and $\sigma NN^*(1440)$ coupling constants.
