In LHC run1, the discovery of Higgs boson are striking success for the Standard Model (SM) again. Although it’s the most well-tested description of modern particle physics available today, SM is powerless in explaining hierarchy problem, dark matter in the observed universe, etc. Beyond-SM theories arise to rescue and one such theory that provides elegant solutions to many outstanding problems in SM is Supersymmetry. Based on LHC-the most powerful collider in the world, CMS experiment has achieved the chance to dig into the new particle production. This presentation will focus on one search of the susy evidence at cms, the analysis topic relies on the top pair +photons and met final state in the natural GMSB model. Currently, LHC is under the run2 data taking period at 13TeV, Run1 results and Run2 progress will be discussed.
