Abstract

We investigate the impact of TeV-scale matter belonging to complete vectorlike multiplets of unified groups on the lightest Higgs boson in the MSSM. We find that consistent with perturbative unification and electroweak precision data the mass mh can be as large as 160 GeV. These extended MSSM models can also render the little hierarchy problem less severe, but only for lower values of mh(125)GeV. We present estimates for the sparticle mass spectrum in these models.
