The race for supersymmetry: Using mT2 for discovery
Abstract
We describe how one may employ a very simple event selection, using only the kinematic variable mT2, to search for new particles at the LHC. The method is useful when searching for evidence of models (such as R-parity conserving supersymmetry), which have a Z2 parity and a weakly interacting lightest parity-odd particle. We discuss the kinematic properties which make this variable an excellent discriminant against the great majority of standard model backgrounds. Monte Carlo simulations suggest that this approach could be used to discover supersymmetry with somewhat smaller integrated luminosities (or perhaps lower center-of-mass energies) than would be required for other comparable analyses.
