GUT's with Adjoint Higgs from Superstrings

Abstract

I discuss how effective grand unified theories requiring adjoint Higgs fields for breaking to the standard model can be contained within string theory. Initial findings are presented in a search for and classification of effective three generation SO(10) SUSY-GUT models built using the free-fermionic string approach. Based on talk presented at PASCOS '94, Syracuse, NY.
