Abstract
摘要 |
The mass hierarchical spectrum of supersymmetric particles in the minimal supersymmetric standard model (MSSM) plays a significant role in determining the new physics signals at the large hadron collider (LHC). We investigate the sparticle mass hierarchical patterns in the framework of the minimal supergravity grand unification (mSUGRA) and SUGRA models with non-universal soft parameters, and then connect the mass patterns to the LHC signature analysis including multi-leptons, multi-jets, and large missing energy. We discuss the phenomenology of the dark matter which is the lightest supersymmetric particle (LSP) in MSSM, including relic abundance, dark matter direct detection and the recent PAMELA anomaly. Also presented are the correlations between the LHC signature and dark matter in the context of the sparticle mass patterns in mSUGRA, and the various experimental constraints on supersymmetry and the implications.
