Electromagnetic form factors and static properties of the nucleon in a relativistic potential model of independent quarks with chiral symmetry

Nucleon charge and magnetic form factors ${G}_{E}$,${\mathit{M}}^{\mathrm{p}}$,n(${\mathrm{q}}^{2}$) have been presented in a quark model with an equally mixed scalar and vector potential in harmonic form taking the pionic contributions into account. The static properties such as the magnetic moment, charge radius, and axial-vector coupling constant in the neutron-\ensuremath{\beta}-decay process are shown to be in excellent agreement with the corresponding experimental values. The role of the finite extension of the quark-pion vertex in determining the charge radius and magnetic moment due to the pion cloud surrounding the nucleons has been studied.
