We investigate an alternative left-right model (ALRM) that is not symmetric under the exchange of fermion content, but can be embedded in E-6 and has a low energy Higgs structure similar to the traditional left-right symmetric models (LRSM). By analyzing the scalar potential and vacuum structure, we ensure the stability of the scalar potential and derive constraints on various coupling parameters through numerical study.
We investigate an Alternative Left-Right Model (ALRM) with SU(2)(L) as well as SU(2)(R) gauge groups, but unlike the traditional left-right symmetric models (LRSM) is not symmetric under the exchange of the fermion content. Interestingly, it can be embedded in E-6, while its low energy Higgs structure resembles the LRSM, involving Higgs doublets X-L,X-R and one Higgs bidoublet phi. We analyze the scalar potential and the vacuum structure of the theory analytically to ensure the stability of scalar potential via bounded from below (BFB) and copositivity criteria, accompanied by a numerical study. We establish the necessary criteria for electric charge-preserving vacua, yielding constraints on various coupling parameters of the theory. Finally we obtain constraints on the parameters of the model from collider data on the masses of the Higgs scalars.
