A microscopic N N → N N*(1440) potential

2004

By means of a NN → N N* (1440) transition potential derived in a parameter-free way from a quark-model based N N potential, we determine simultaneously the πN N*(1440) and σ N N* (1440) coupling constants. We also present a study of the target Roper excitation diagram contributing to the p(d,d’) reaction.

Quark-model based study of the triton binding energy

2001

The three-nucleon bound state problem is studied employing a nucleon-nucleon potential obtained from a basic quark-quark interaction in a five-channel Faddeev calculation. The obtained triton binding energy is comparable to those predicted by conventional models of the $NN$ force.
