Spectrum of states in the one-dimensional t'Hooft model
Marinov M.S., Perelomov A.M., Terent'ev M.V.
We consider the theory of spinor and vector fields in two-dimensional space-time; this theory is invariant with respect to the internal symmetry group SU(N). The interaction is of the Yang-Mills type. The model can be solved in the limit as e2~iV"'—Ю (e is the coupling constant). The mass spectrum of the fermion-antifermion system, previously obtained by t'Hooft by summing a certain class of Feynman diagrams, is obtained.
