Baryon Magnetic Moments in the 1/Nc Expansion with Flavor Symmetry Breaking
Abstract
The magnetic moments and transition magnetic moments of the ground state baryons are analyzed in an expansion in 1/Nc, SU(3) flavor symmetry breaking and isospin symmetry breaking. There is clear evidence in the experimental data for the hierarchy of magnetic moments of the combined expansion in 1/Nc and flavor breaking. SU(3) breaking in the magnetic moments is expected to be enhanced relative to that of other hadronic observables, and significant SU(3) breaking is found.
