Query: Baryon moments in a QCD-based model   We have analyzed the theory of the baryon magnetic moments in the
approximate) QCD setting suggested by Brambilla et al. By modifying their
derivation of the $qqq$ interaction and wave equation for baryons, we derived
expressions for the baryon moments in terms of the underlying quark moments,
including the first corrections associated with the binding of the quarks in
baryons. The results, which hold in the ``quenched approximation'' in which the
contributions of virtual quark pairs are neglected, fail to describe the
measured moments, with typical errors on the order of 7%. We conclude from our
analysis that the quenched approximation is at fault, and that the baryon
moments give a sensitive test of that standard approximation in the lattice and
analytic approaches to QCD.
