Supersymmetry as the nearest option beyond the standard model

摘要

The present lectures contain an introduction to possible new physics beyond the Standard Model. Having in mind first of all accelerator experiments of the nearest future we concentrate on supersymmetry, a new symmetry that relates bosons and fermions, as the first target of experimental search. The motivation to introduce supersymmetry is discussed. The main notions of supersymmetry are introduced. The supersymmetric extension of the Standard Model—the minimal supersymmetric standard model (MSSM)—is considered in more detail. Phenomenological features of the MSSM as well as possible experimental signatures of SUSY at hadron colliders are described.
