Abstract:

In this talk I will review the ways that compactifications of the heterotic string can be subject to constraints on the matter couplings of the 4-dimensional effective theory that do not arise from gauge symmetries. Such "topological vanishings" have the potential to be useful for the realization of certain mass hierarchies (such as in the famous "mu problem") or dangerously restrictive on the physical theories. I will describe and compare several different ways that topological vanishings arise in heterotic theories and new results that indicate they may be a generic feature of such compactifications.
