A Chiral Quark-Soliton Model Theory for Nuclear Force

Abstract: The chiral quark-soliton model with one gluon exchange is briefly described. The quark-gluon coupling constant and quark wave functions determined in the soliton model are used as input for the relativistic two-quark-cluster theory. In this paper the two-nucleon system is studied. Two terms of the kinetic energy and relative-motion energy in the quark-exchange kernel are taken into account. Therefore, the phase shifts for 3S1 and 1S0 channels are improved. The phase shifts are in agreement with Arndt's. It is shown by our calculations that one-gluon-exchange and quark-exchange provide a short-range repulsive potential and the chiral field produces the middle- and long-rang attractive potential.
