dc.descriptionWe calculate S-wave singlet and triplet NN phase shifts stemming from the short-range flavor-spin hyperfine interaction between constituent quarks using the resonating group method approach. A strong short-range repulsion is found in both waves. A fair comparison is performed between the traditional picture, relying on the colour-magnetic interaction, and the present one, relying on the Goldstone boson exchange dynamics. It is shown that the latter one induces essentially stronger repulsion, which is a very welcome feature. We also study a sensitivity of phase shifts and wave function to extention from the one-channel to three-channel resonating group method approximation.
