Query: Baryon quadrupole moment in the 1/N(c) expansion of QCD   The quadrupole moments of ground state baryons are discussed in the framework
of the 1/N(c) expansion of QCD, where N(c) is the number of color charges.
Theoretical expressions are first provided assuming an exact SU(3) flavor
symmetry, and then the effects of symmetry breaking are accounted for to linear
order. The rather scarce experimental information available does not allow a
detailed comparison between theory and experiment, so the free parameters in
the approach are not determined. Instead, some useful new relations among
quadrupole moments, valid even in the presence of first-order symmetry
breaking, are provided. The overall predictions of the 1/N(c) expansion are
quite enlightening.
