Magnetic Moments of the Octet Baryons in a Chiral Quark Potential Model

Abstract

In quark potential models, two--body current contributions to baryon magnetic moments arise necessarily to satisfy the continuity equation for the electromagnetic current. On the other hand, the naive additive quark model predicts the experimental octet magnetic moments to within 5$\%$. We demonstrate that consistently derived two--body current contributions to the octet baryon magnetic moments are individually large, but tend to cancel each other globally.
