The edge of supersymmetry: Stability walls in heterotic theory

Abstract:

We explicitly describe, in the language of four-dimensional N = 1 supersymmetric field theory, what happens when the moduli of a heterotic Calabi-Yau compactification change so as to make the internal non-Abelian gauge fields non-supersymmetric. 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 four-dimensional theory. The D-term contribution to the scalar potential associated to this U (1) attemp...
