摘要
The couplings and interactions of baryons containing a heavy quark are related by light quark spin-flavor symmetry in the large N limit. The single pion coupling constant which determines all heavy quark baryon-pion couplings is equal to the pion coupling constant for light quark baryons. Light quark symmetry relations amongst the baryon couplings are violated at order 1/N2. Heavy quark spin-flavor symmetry is used in conjunction with large N light quark spin-flavor symmetry to determine the couplings of the degenerate doublets of heavy quark baryons.
