Query: Phenomenology of Non-Abelian Flat Directions in a Minimal Superstring
  Standard Model   Recently, we presented the first non-Abelian flat directions that produce
from a heterotic string model solely the three-generation MSSM states as the
massless spectrum in the observable sector of the low energy effective field
theory. In this paper we continue to develop the systematic techniques for the
analysis of nonrenormalizable superpotential terms and non-Abelian flat
direction in realistic string models. Some of our non-Abelian directions were
F-flat to all finite orders in the superpotential. We study for the same string
model the varying phenomenologies resulting from a large set of such all-order
flat directions. We focus on the quark, charged lepton, and Higgs doublet mass
matrices resulting for our phenomenologically superior non-Abelian flat
direction. We review and apply a string-related method for generating large
mass hierarchies between MSSM generations, first discussed in string-derived
flipped SU(5) models, when all generational mass terms are of renormalizable or
very low non-renormalizable order.
