Abstract: This thesis work is meant as an introduction to supersymmetry and its phenomenological implications for the basic features of the standard model of electroweak interactions, it continues with a through denition and basic derivation of the fundamental concepts of supersymmetric eld theories, including superspace, supereld and superpotential.In a supersymmetric theory, all interactions are to be symmetric under the exchange of bosons and fermions { the superpartners. However, supersymmetry must be an explicitly yet softly broken symmetry of nature, and supersymmetry breaking parameters, the so-called soft terms, give rise to various phenomena observable at present and future experiments. The mixing among different flavors of matter-the flavor violation { is one such phenomenon which exhibits a strong dependence on the structure of the soft terms. In particular, decoupling of superpartners from the particle spectrum at a threshold energy near the ultraviolet scale of the standard model induces sizeable corrections to flavor violating interactions. These correctionsare strong enough to disqualify an otherwise viable high-scale flavor model by a confrontation with experiments at low energy. This thesis work focusses a class of flavor models, following from strings or supergravity, and provides a through analysis of their sensitivities to supersymmetric threshold corrections.
