    • Abstract

       

      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 ($\chi$ 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 $(n, \sum^{0}, \Xi, \Lambda)$ and decuplet $(\Lambda^{0}, \sum^{*0}, \Xi^{*0})$ baryons.
