| Sumario: | In the LHC searches for gluinos it is usually assumed that they decay predominantly into the lightest neutralino plus jets. In this work we perform a proof-of-concept collider analysis of a novel supersymmetric signal in which gluinos decay mostly into jets and the bino-like neutralino (χ˜ 0 3), which in turn decays into the lightest Higgsino-like neutralino (χ˜ 0 1), considered the dark matter candidate, together with the SM-like Higgs boson (h). This new physics signal then consists of an LHC final state made up by four light jets, four b-jets, and a large amount of missing transverse energy. We identify t¯t, V þ jets (V ¼ W, Z), and t¯t þ X (X ¼ W, Z, γ, h) productions as the most problematic backgrounds, and develop a search strategy for the high luminosity phase of the LHC, reaching signal significances at the evidence level for a luminosity of 1000 fb−1. The prospects for a luminosity of 3000 fb−1 are even more promising, with discovery-level significances.
