Octet Baryons

The magnetic moments of the octet baryons are calculated in a chiral symmetric inde-pendent quark potential model of the form [Formula: see text] The residual interaction arising from the quark-pion coupling over and above the dominant confining one represented by this phenomenological potential, is treated as a low order perturbation. The correction due to center of mass motion is also taken into account appropriately. The results are in reasonable agreement with the experimental data.

Octet Baryons

A simple independent-quark model based on the Dirac equation with an equally mixed scalar–vector linear confining potential model is used to obtain a fit for the electromagnetic properties — like the magnetic moments, charge radii and axial-vector coupling-constant ratios — of octet baryons, taking into account the appropriate center-of-mass corrections. This fit is extended to include the quark-core contributions to the nucleon electromagnetic form factors [Formula: see text], [Formula: see text], [Formula: see text] and the axial-vector form factor GA(q2). The respective root-mean-square radii associated with [Formula: see text] and GA(q2) come out as [Formula: see text] and [Formula: see text]. The possibility of restoring in this model the chiral symmetry in the usual way is discussed and the pion-nucleon coupling constant is found as gπ NN = 13.72 as compared to (gπ NN ) exp ≃ 13.

Octet Baryons

Under the assumption that baryons are an assembly of independent quarks confined in a first approximation by an effective potential [Formula: see text], 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.
