Abstract
Recent baryon magnetic moment measurements are used to isolate individual quark magnetic moment contributions, including nonstatic effects. The pattern of symmetry breaking observed is that quarks in spin-triplet states preserve SU(3), while quarks in spin-singlet states break SU(3). Relativistic effects are suggested as the dominant symmetry breaking mechanism. The present moment determination is incompatible with this analysis.
