Scalar Mass Universality,``Anomalous'' U(1) and R Symmetries
Abstract
When the supersymmetric theory contains the ``anomalous'' U(1) gauge symmetry with GreenSchwarz anomaly cancellation mechanism in four dimensions, FayetIliopoulos Dterm generates generically nonuniversal scalar masses and the positive cosmological constant after the supersymmetry breaking. Both give the new contributions to the known results obtained from Fterm. Our mechanism is naturally realized in many string models and in some cases, leads to remarkable cancellations between F and Dterm contributions, providing the universal scalar mass and vanishing cosmological constant. We illustrate how such a possibility can arise by taking a simple orbifold example.
