SUSY SEARCHES AT LHC AND DARK MATTER

摘要

Supersymmetric models with R-parity conservation provide an excellent can-didate for Dark Matter, the Lightest Supersymmetric Particle, which will be searched for with the ATLAS detector at the Large Hadron Collider (LHC). Based on recent simulation studies, we present the discovery potential for Supersymmetry (SUSY) with the first few fb~(-1) of ATLAS data, as well as studies of the techniques used to reconstruct decays of SUSY particles at the LHC. We further discuss how such measurements can be used to constrain the underlying Supersymmetric model and hence to extract information about the nature of Dark Matter.
