CLASSIFICATION OF PARTICLES AT ARBITRARY QUANTITY OF GENERATIONS. II. LEPTONS

The hypothesis on quark nature of the leptons is proposed. Leptons are compacted q3 -systems. It ensures the equality of modules for the electric charges of the proton and the electron. The classification of particles based on the U(Nf,g)×SU(3,c)×SU(4,fs)×O(3) -group is proposed at arbitrary quantity Nf of the quark generations. The U(Nf,g) -group corresponds to the quark generations, the SU(3,c) -group describes the color variables, the SU (4,fs) - group corresponds to the variables in the spin (s) and flavor (f) spaces, and the O(3) -group describes the orbital excitations of quarks. In consequence of the Pauli principle leptons consist of antiquarks from 3 different generations. Minimal quantity of leptons with definite electric charge equal 20. Excited double charged (l−−) -leptons and (l++) -antileptons with the J^p=(1/2)+ and J^p=(1/2)- are predicted, respectively. They can be resonances in e−π−, e−K−, e+π+, e+K+, μ−π−, μ−K−, μ+π+, μ+K+ -systems.
