Introductory Low-Energy Supersymmetry
Howard E. Haber
Abstract
Low-energy supersymmetry is a theoretical extension of the Standard Model of particle physics in which supersymmetry is invoked to explain the origin of the electroweak scale. In this approach, the energy scale of supersymmetry breaking can be no larger than about 1 TeV. In these lectures, a pedagogical account of softly broken supersymmetric gauge theories is presented. The minimal supersymmetric extension of the Standard Model (MSSM) is defined and constraints on its parameters are explored. The implications of supersymmetric tree-level interactions and its one-loop corrections are discussed. Low-energy supersymmetric model alternatives to the MSSM are briefly mentioned.
