Top jets as a probe of degenerate stop-NLSP LSP scenario in the   framework of cMSSM
  The degenerate stop NLSP and neutralino LSP scenario is well motivated but hard to detect at the collider experiments. We propose a novel signature for detection this scenario at the Large Hadron Collider (LHC) and demonstrate its feasibility.
