We study gaugino condensation in presence of an anomalous U(1) gauge group and find that global supersymmetry is dynamically broken. An example of particular interest is provided by effective string models with 4dimensional Green-Schwarz anomaly cancellation mechanism. The structure of the hidden sector is constrained by the anomaly cancellation conditions and the scale of gaugino condensation ...

We examine the soft supersymmetry breaking parameters that result from various ways of embedding the Standard Model (SM) on Dbranes within the Type I string picture, allowing the gaugino masses and μ to have large CPviolating phases. One embedding naturally provides the relations among soft parameters to satisfy the electron and neutron electric dipole moment constraints even with large phases,...

QCD-like hidden sector models of supersymmetry breaking are considered which do not suffer from a cosmological problem due to the Polonyi field. Avoidance of a light gluino leads to introduction of quasi-symmetry – symmetry broken explicitly only through gravitational effects. ⋆ JSPS Research Fellow.
