Supersymmetry in Elementary Particle Physics
نویسنده
چکیده
These lectures give a general introduction to supersymmetry, emphasizing its application to models of elementary particle physics at the 100 GeV energy scale. I discuss the following topics: the construction of supersymmetric Lagrangians with scalars, fermions, and gauge bosons, the structure and mass spectrum of the Minimal Supersymmetric Standard Model (MSSM), the measurement of the parameters of the MSSM at highenergy colliders, and the solutions that the MSSM gives to the problems of electroweak symmetry breaking and dark matter. lectures presented at the 2006 TASI Summer School Boulder, Colorado, June 4–30, 2006 1Work supported by the US Department of Energy, contract DE–AC02–76SF00515.

Hidden Supersymmetry
Inspired by the concept of complementarity, we present a illustrative model for the weak interactions with unbroken gauge symmetry and unbroken supersymmetry. The observable particles are bound states of some more fundamental particles. Supersymmetry is broken at the macroscopic scale of the observable particles by a discrete symmetry but remains exact at the scale of the fundamental particle a...
متن کاملLow-Energy Supersymmetry: Prospects and Challenges
An introduction to the minimal supersymmetric Standard Model (MSSM) is given. The motivation for “low-energy” supersymmetry is reviewed, and the structure of the MSSM is outlined. In its most general form, the MSSM can be viewed as a low-energy effective theory parametrized by a set of arbitrary soft-supersymmetry-breaking parameters. A variety of techniques for reducing the parameter freedom o...
متن کاملSupersymmetry and Neutrino Masses
Neutrino masses are zero in the minimal supersymmetric standard model. I discuss how they may become nonzero with new interactions which may or may not violate R-parity conservation. ———————– Talk presented at the 6th Corfu Summer Institute on Elementary Particle Physics, 1998.
متن کاملPhenomenological Aspects of Supersymmetry
We discuss the possible applications supersymmetric theories might nd in the eld of elementary particle physics. The supersymmetric generalization of the SU(3) SU(2) U(1) standard model is discussed in detail. Special attention has been devoted to the question of gauge coupling constant uni cation in the framework of supersymmetric grand uni ed models. * Lecture given at the conference "Gauge T...
