The LHC has collected data for more than eight years, but no clear signal for new physics has emerged so far. This is surprising because there is overwhelming evidence that the Standard Model must be extended. One such extension is SUSY. Here, new scalar and fermions at the TeV scale are predicted but the null results at the LHC have ruled out large region of its parameter space. However, many searches assume that large missing transverse energy is present in the signal. In the so-called stealth SUSY scenarios, new light almost degenerate fermion/boson pairs with weak scale supersymmetric masses are introduced which result in significantly reduced missing transverse energy. In this talk we want to investigate the discovery potential of such stealth SUSY models at the LHC. We reconstruct the decay products by using a large-radius jet containing a high transverse momentum photon, which has not been used in experiments so far. Requirements on the event topology, and use of substructure variables result in orders of less background than signal.
