| Abstract | To escape the current LHC supersymmetry (SUSY) search constraints while preserving the naturalness condition, we propose the heavy lightest supersymmetric particle (LSP) SUSY. According to the different dependencies on the LSP mass, we systematically classify the discriminating variables into three categories. We find that the strong dependence of all current SUSY searches on variables in the first category render weak sensitivity for the heavy LSP SUSY. In particular, all the current LHC SUSY search constraints can be evaded if the LSP mass is around 600 GeV or higher. In the minimal supersymmetric standard model (MSSM), we find that the heavy LSP SUSY does not induce more fine-tuning than the Higgs boson mass. Moreover, the muon anomalous magnetic moment can be satisfied within the 3-s level. We systematically study the viable parameter space for the heavy LSP SUSY and present four benchmark points that realize our proposal concretely. An improved collider search for those benchmark points, which mainly relies on the variable in the second category, is discussed in detail. |
