Nucleon core size and nucleon-nucleon spin-orbit forces

Possibility of restoring chiral symmetry in quantum chromodynamics

“…For values of the gluon condensate Cg = (380-420 MeV) ~ and constant F~ = 93 MeV, solving (4.7), we get R c = (0.42-0.27) fm. This estimate of Rc is completely reasonable from current representations of the scale of loss of chiral symmetry and estimates of the size of the nucleon core in quark models [14]. Thus, the study of soliton--baryons on the basis of effective potential (4.6) uncovers interesting possibilities for the construction of a realistic nucleon-nucleon potential with quark--gluon core.…”
