The mass spectrum of the model is symmetric with respect to particle-antiparticle exchange. The quantum model contains elementary particles and the cluster states generating infinite degeneracy of the mass spectrum.12 pages, 1 figure, the paper accepted for publication in Advances in Applied Clifford AlgebraHigh Energy Physics - Theorytext
