Abstract
The problem of generations (families) of fermions remains one of the central problems of elementary particle physics. The standard gauge model SU(3)⊗SU(2)⊗U(1), as well as its ‘vertical’ extensions, based on gauge groups of unification SU(5), SU(10), and so on, are built into one fermion generation. These models do not contain any deep physical causes of the mass hierarchy between generations of fermions and the observed smallness of mixing angles.
