| Abstract: | It is demonstrated that the spontaneous breakdown ofCP invariance in grand unified theories requires the presence of intermediate mass scales. The simplest realization is provided by weakly broken left-right symmetry in the context ofSU(2)L×SU(2)R×U(1) B?L model embedded in grand unified theories. |
