TH Theory Conference Room (CERN)

In this talk I will first review (in the context of 4D N=1 effective supergravity theories) when a generic theory involving chiral and vector multiplets can admit metastable vacua with spontaneously broken supersymmetry and negligible cosmological constant. I will then show how the existence of such vacua implies strong necessary conditions on the parameters of the theory. In particular I will show how these conditions constrain the Kahler curvature for the scalar geometry, the charge and mass matrices for the vector fields, and the vector of F and D auxiliary fields (which is constrained to lie within a certain domain). I will also discuss the relevance and implications of these general results on effective theories arising from string compactifications.
