Baryon structure in the global color symmetry model of QCD Original Research Article

Baryons are considered as solitons in the global color symmetry model (GCM) of QCD. With both the scalar and pseudoscalar chiral fields being included and the Hedgehog approximation being taken, we obtain a GCM soliton profile whose mass and radius are quite close to the experimental data of a nucleon. We then quantize the angular momentum and isospin with the collective quantization method and obtain a nucleon-Delta mass split comparable with experimental data.
