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 (), which in turn decays into the lightest Higgsino-like neutralino (), considered the dark matter candidate, together with the SM-like Higgs boson (). This new physics signal then consists of an LHC final state made up by four light jets, four -jets, and a large amount of missing transverse energy. We identify , (, ), and (, , , ) 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 . The prospects for a luminosity of are even more promising, with discovery-level significances.
