Vacuum structure of Alternative Left-Right Model

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