Model-Independent Analysis of Soft Terms in Effective Supergravity and in String Theory

Abstract

We discuss supersymmetry breakdown in effective supergravities such as emerge in the low-energy limit of superstring theory. Without specifying the precise trigger of the breakdown, we analyse the soft parameters in the Lagrangian of the supersymmetrized Standard Model.Comment: CERN-TH.6809/93, UTTG-05-93, PHYZZX macros required, 13 page
