Query: CP Violation and Moduli Stabilization in Heterotic Models   The role of moduli stabilization in predictions for CP violation is examined
in the context of four-dimensional effective supergravity models obtained from
the weakly coupled heterotic string. We point out that while stabilization of
compactification moduli has been studied extensively, the determination of
background values for other scalars by dynamical means has not been subjected
to the same degree of scrutiny. These other complex scalars are important
potential sources of CP violation and we show in a simple model how their
background values (including complex phases) may be determined from the
minimization of the supergravity scalar potential, subject to the constraint of
vanishing cosmological constant.
