Event shape variables in supersymmetry searches at 7 TeV LHC

Supersymmetry (SUSY) signatures are probed at the Large Hadron Collider with 7?TeV energy in the framework of CMSSM with a new set of cuts based on event shapes and jet energy scales. It is showed that with our cuts, it is possible to probe a large portion of CMSSM parameter space in situations, where the SUSY cascade decay chain produces hard multijets + missing energy. We also extend our analysis to include other supersymmetries which produce hard multijets + missing energy.
