Reconciling GA/GV, <rn2> and μp,n in Chiral Quark Model with one Gluon Generated Configuration Mixing
Abstract
The spin polarization functions ( u, ~ d, ~ s) for proton are calculated in the chiral quark model () with SU(3) symmetry breaking as well as configuration mixing generated by one gluon exchange forces for the NMC and the most recent E866 data. Besides reproducing the spin polarization functions u, d, s as well as GA/GV, it can accomodate nucleon magnetic moments and neutron charge radius as well, thus resolving the compatibility problem of these parameters which could not be achieved in constituent quark models.
