MAGNETIC-MOMENTS OF OCTET BARYONS IN A RELATIVISTIC QUARK-MODEL WITH CHIRAL-SYMMETRY

Under the assumption that baryons are an assembly of independent quarks confined in a first approximation by an effective potential V(q)(r) = 1/2 (1 + gamma0)(a2r + V0), which presumably represents the nonperturbative gluon interactions, the magnetic moments of octet baryons have been calculated by considering perturbatively the contributions of the residual quark-pion coupling arising out of the requirement of chiral symmetry over and above the necessary center-of-mass correction. The results so obtained agree quite well with the corresponding experimental values.
