transitions. The implications of such a model have been investigated in detail for the effects of symmetry breaking and GPM parameters pertaining to the one-, two-, and three-quark contributions. Our results are not only comparable with the latest experimental studies but also agree with other phenomenological models. It is found that the
χ
CQM is successful in giving a quantitative and qualitative description of the charge radii and quadrupole moments. |
