Susy Terminology
- SUSY - Supersymmetry !
- 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
