Parameter Space Investigations of Free Fermionic Heterotic Models
Abstract
I survey the parameter space of NAHE-based free fermionic heterotic string models. First, I discuss flat directions of the low energy effective field theories and show that D-flat directions need not be isomorphic to gauge invariant superpotential terms. Next, I review recent studies of three generation SU(3)C × SU(2)L ×U(1)Y, SU(3)C × SU(2)L × SU(2)R × U(1)B-L, SU(4)C × SU(2)L × U(1)Y', and flipped SU(5) models, constructed by Wilson breaking of the underlying SO(10) observable sector gauge group of the NAHE &Z;2 × &Z;2 basis.
