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' $(\approx m_t/m_b)$ $\tan β$ regions by studying the variations of $r (\equiv \sqrt{μ^2_{1,2}/μ^2_3})$, where $μ^2_{1,2,3}$ are the well known MSSM parameters evaluated at the GUT scale. For $r$ sufficiently close to unity the quantity $\tan β$ can be of order unity, but the converse is not always true.
