| Abstract: | The possibility of introducing the discrete symmetry D is studied, which along with SUc(3) × SUL(2) × U(1)-symmetry, remains after the breaking of SO(N) grand unified symmetry by the Higgs fields vevs ～ 1015 GeV. The D quantum number distinguishes the fermions coupled with W-bosons via left and right currents. As a result, the presence of low-mass fermions in the theory is provided. |
