Dynamical supersymmetry breaking

Abstract

Dynamical supersymmetry breaking is a fascinating theoretical problem that is also of phenomenological significance. A better understanding of this phenomenon can help in model building, which in turn is useful in guiding the search for supersymmetry. This article reviews recent developments in the field, discussing a few examples to illustrate the main ideas. In the process, we show how the techniques of holomorphy and duality come into play and how they have helped in the study of gauge-mediated supersymmetry breaking. The review is intended for readers with a prior knowledge of supersymmetry who want to find out about the recent progress in this field.
