【 摘 要 】

The charge radii of the spin-$dfrac{1}{2}^{+}$ octet and spin-$dfrac{3}{2}^{+}$ decuplet baryons have been calculated in the framework of chiral constituent quark model (𝜒 CQM) using a general parametrization method (GPM). Our results are not only comparable with the latest experimental studies but also agree with other phenomenological models. The effects of 𝑆𝑈(3) symmetry breaking pertaining to the strangeness contribution and GPM parameters pertaining to the one-, two- and three-quark contributions have also been investigated in detail and are found to be the key parameters in understanding the non-zero values for the neutral octet $(n, sum^{0}, Xi, 𝛬)$ and decuplet $(𝛬^{0}, sum^{*0}, Xi^{*0})$ baryons.
