The stability of the predictions of two of the standard model parameters, α 3 (M Z ) and sin 2 θ(M Z ), in a M U ∼ 4 TeV unification model is examined. It is concluded that varying the unification scale between M U 2.5 TeV and M U 5 TeV leaves robust all predictions within reasonable bounds. Choosing M U = 3.8 ± 0.4 TeV gives, at lowest order, accurate predictions at M Z . The impact of threshold effects on unification depends on the spectrum of states beyond the standard model. 

“…The above analysis shows that the structure of the neutral gauge bosons is the same as that of the RM331 model when all mixing and mass parameters of these bosons are written in term of the charged gauge boson masses. So the contributions of new heavy gauge bosons to the ρ parameter from the SU(3) L charged gauge bosons are given in [79,80]. They also relate to the T parameter through the equality ∆ρ ≡ ρ − 1 ≃ α(m Z )T , where α(m Z ) is the fine structure constant defined in the minimal scheme (MS) at the m Z scale [81].…”

Masses and signals of the production of Doubly charged Higgses (DCH) in the framework of the supersymmetric reduced minimal 3-3-1 model (SUSYRM331) are investigated. In the DCH sector, we prove that there always exists a region of the parameter space where the mass of the lightest DCH is in order of O(100) GeV even when all other new particles are very heavy. The lightest DCH mainly decays to two same-sign leptons while the dominated decay channels of the heavy DCHs are those decay to heavy particles. We analyze each production cross section for e + e − → H ++ H −− as a function of a few kinematic variables, which are useful to discuss the creation of the DCHs in the e + e − colliders as a signal of new physics beyond the Standard Model. The numerical study shows that the cross sections for creating the lightest DCH can reach values of few pbs. The two other DCHs are too heavy, beyond the observable range of experiments. The lightest DCH may be detected by the International Linear Collider (ILC) or the Compact LInear Collider (CLIC) bysearching its decay to a same-sign charged lepton pair. PACS numbers: 11.15.Ex, 12.60.Fr, 13.66.Fg H ± 1 behaving the same as those in the MSSM. More explicitly, they couple with W and Z boson the in same way as those in the MSSM, especially in the large limit of the SU(3) L and soft SUSY breaking scales, which is exactly the valid condition of the SUSYRM331.So the total contribution to the ρ parameter of these SUSYRM331 Higgses is nearly the
