Radiative Electroweak Breaking with Pseudogoldstone Higgs Doublets

Abstract

We consider a realistic example of supersymmetric grand unification based on $SU(3{)}_c\times SU(3{)}_L\times SU(3{)}_R$ in which the electroweak (EW) higgs doublets are `light' as a consequence of the `pseudogoldstone' mechanism. We discuss radiative EW breaking in this model, exploring in particular the `small' (order unity) and `large' $(\approx m_t/m_b)$ $\tan \beta$ regions by studying the variations of $r(\equiv \sqrt{{\mu }_{1,2}^2/{\mu }_3^2})$, where ${\mu }_{1,2,3}^2$ are the well known MSSM parameters evaluated at the GUT scale. For $r$ sufficiently close to unity the quantity $\tan \beta$ can be of order unity, but the converse is not always true.
