Susy Terminology

• SUSY - Supersymmetry !
• MSSM - Minimal Supersymmetric extension of the Standard Model
• mSUGRA -
• LSP - Lightest Supersymmetric Particle. In most model the lightest neutralino is LSP, but in some model it is the gravitino.
• NLSP - Next to Lightest Supersymmetric Particle
• Coannihilation region - Region in SUSY parameters space where the mass difference between NLSP and LSP is small (few GeV). This enhances the probability of NLSP and LSP annihilating with each other bringing the relic density down to a level consistent with astrophysical observations.
• Drell-Yan process - Quark+anti-quark -> Z/photon -> lepton+anti-lepton
• OS-SF - Opposite sign same flavour
• SUSY benchmark points - points in SUSY parameter space which are chosen as test points in simulation studies. The benchmark points are chosen such that they are representative for different regions of the parameter space
  • SPS1: "Typical" mSUGRA scenario
  • SPS2: "Focus point" scenario in mSUGRA
  • SPS3: Model line into "coannihilation region" in mSUGRA
  • SPS4: mSUGRA scenario with large tan β
