## Supersymmetry

This is a collection of links to video lectures related to supersymmetry from CERN. Supersymmetry is a proposed symmetry of nature relating two basic classes of elementary particles: bosons and fermions.

Video/text | Supersymmetric Recipes |

Description | By Benjamin Allanach, 2011. In these lectures, I shall describe the theory of supersymmetry accessible to people with a knowledge of basic quantum field theory. The lectures will contain recipes of how to calculate which interactions (and which special relations) are in supersymmetry, without providing detailed proofs of where they come from. ... |

Video/text | Introduction to supersymmetry |

Description | By D. Kaplan, 2007. In these lectures, I will introduce supersymmetry as an extension to spacetime symmetries both formally and physically. I will present motivations for why we think supersymmetry may exist in the real world, and may manifest itself at the LHC. ... |

Video/text | Searching for Supersymmetry at the LHC |

Description | By F. Gianotti, 2003. We will review the general motivations for proposing non-standard descriptions of fundamental interactions. We will give a simple and pedagogical presentation of the theoretical foundations of Supersymmetry, and we will describe the main features of a realistic supersymmetric extension of the Standard Model. We will present the phenomenology expected in several motivated scenarios. ... |

Video | Introduction to physics beyond the Standard Model |

Description | By G. Giudice, 1998. These lectures will give an introductory review of the main ideas behind the attempts to extend the standard-model description of elementary particle interactions. After analysing the conceptual motivations that lead us to believe in the existence of an underlying fundamental theory, we will discuss the present status of various theoretical constructs : grand unification, supersymmetry and technicolour. ... |

Video | Beyond the Standard Model |

Description | By Antonio Masiero, 1997. A critical reappraisal of the Standard Model (SM) will force us to new physics beyond it. I will argue that we have good reasons to believe that the latter is likely to lie close to the electroweak scale. After discussing the possibility that such new physics may be linked to a dynamical breaking of SU(2)xU(1) (technicolour), I will come to the core of the course: low energy supersymmetry. ... |

Video | Supersymmetry and particle physics |

Description | By Hans Peter Nilles, 1995. Theoretical and phenomena-logical properties of supersymmetric extension of the SU (3)xSU (2)xSU (1) standard model and its grand unified versions are discussed in detail. We give an introduction to supersymmetry and supergravity and review attempts to construct models in which the breakdown scale of weak interactions is related to supersymmetry breakdown. ... |

Video | Introduction to supersymmetry for particle physics |

Description | By Sergio Ferrara, 1994. Lectures: 1, An introduction to space-time symmetries: Poincare and conformal invariance. 2, What is supersymmetry? Fermi-Bose symmetries, multiplets and currents. 3, Construction of supersymmetric interactions: Yukawa couplings and Yang-Mills theories. 4, Spontaneous and explicit supersymmetry breaking. 5, Softening of quantum divergences: the hierarchy problem, the supersymmetric standard model. ... |
