Dyon Three-Triplet Model of Hadrons

Schwinger's composite model of hadrons, based on dyons, is formulated as a dyon three-triplet model with the postulated symmetry group SU(3)[electric] ⊗ SU(3)[magnetic]. The hadron spectrum is dominated by the superstrong magnetic-charge exchange forces; we find the first "exotic" states to be in the meson channel of the ($2D2\overline{D}$) system. This model possesses the good features of the quark model and explains its paradoxes.
