英文摘要: The effective dimension-5 operators can be induced by quantum gravity or inspired by string and M theories. They have important impacts on grand unified theories. We investigate their effects for the well known E(6) model. Considering the breaking chains E-6 bar right arrow H = SO(10) x U-V'(1) bar right arrow SU(5) x U-V(1) x U-V'(1) bar right arrow SU(3) x SU(2) x U-Z(1) x U-V(1) x U-V'(1) and E-6 bar right arrow H = SO(10) x U-V'(1) bar right arrow SU(4) x SUL(2) x SUR(2) x U-V'(1) bar right arrow SU(3) x SUL(2) x SUR(2) x U-S(1) x U-V'(1), we derive and give all of the Clebsch-Gordan coefficients Phi((r))(s,z) associated with E-6 breaking to the Standard Model (SM). Physical effects of nonzero vacuum expectations of SM singlets Higgs in E-6 grand unified theories are discussed.
