The edge of supersymmetry: Stability walls in heterotic theory
Abstract
We explicitly describe, in the language of fourdimensional N = 1 supersymmetric field theory, what happens when the moduli of a heterotic CalabiYau compactification change so as to make the internal nonAbelian gauge fields nonsupersymmetric. At the edge of the region in Kähler moduli space where supersymmetry can be preserved, an additional anomalous U(1) gauge symmetry appears in the fourdimensional theory. The Dterm contribution to the scalar potential associated to this U(1) attempts to force the system back into a supersymmetric configuration and provides a consistent lowenergy description of gauge bundle stability.
