▪ Abstract A spin-flavor symmetry emerges for baryons in the large-N c limit. Large-N c baryons form irreducible representations of the spin-flavor algebra, and their static properties can be computed in a systematic expansion in 1/N c . Symmetry relations for static baryon matrix elements are obtained at various orders in the 1/N c expansion by neglecting subleading 1/N c corrections. Equivalent relations arise in the quark and Skyrme models, which satisfy the same large-N c group theory as quantum chromodynamics (QCD). The 1/N c expansion yields useful results for QCD baryons with N c = 3.
