Saturation in triplet models of hadrons

Triplet models of hadrons are studied according to the criterion of saturation, namely, that the lowest-lying baryons contain exactly three triplets. Two main types of saturation are discussed: Pauli saturation, which depends on antisymmetrization of wave functions, and Coulomb saturation, which relies on the scheme of forces among the particles. The quark, quark-plus-singlet-core, two-triplet, three-triplet, and paraquark models are surveyed, and, using the saturation mechanisms discussed in the text, all of the models are made to satisfy the saturation criterion with the sole notable exception of the quark model, which fails.
