Model-independent analysis of experimental baryon magnetic moments
Journal Article

· Phys. Rev. D; (United States)
Strong disagreement between experimental hyperon magnetic moments and simple model predictions is exhibited in the function R(p, ..sigma../sup +/, ..xi..) = 3(..mu../sub p/-..mu..+)/(..mu..- -..mu..0) = 2.7 +- 0.8, an order of magnitude larger than the broken-SU(6) prediction 0.34. This is shown to imply quenching of contributions of nonstrange quarks in strange-baryon magnetic moments, relative to contributions in the nucleon. The model-independent analysis includes SU (6)-symmetry breaking, configuration mixing, relativistic corrections, and quark-diquark correlations.
