Comparisons of magnetic charge and axial charge meson cloud distributions in the PCQM

Abstract The meson cloud distributions in r-space are extracted from the nucleon electromagnetic and axial form factors which are derived in the perturbative chiral quark model. The theoretical results indicate that the magnetic charge and axial charge distributions of the three-quark core have the...
