Influence of the nucleon - channel on the nucleon - nucleon phase shifts in a chiral-quark model
1997
The influence of the nucleon - multi-channel on nucleon - nucleon phase shifts is studied as a coupled-channel problem in the framework of the resonating group method by using the quark-cluster model with chiral symmetry. It can be seen that additional attraction is generated in the nucleon - nucleon interaction by the coupling to the channel. The mechanism of couplings to nucleon - channels plays an important role in the isotriplet P-wave nucleon - nucleon interaction and solution to the spin - orbit problem, while couplings to the nucleon - channel have a smaller effect on higher partial waves.
