The analyzed data sample corresponds to an integrated luminosity of 138 fb$^{-1}$ . A wide range of potential sparticle signatures are targeted, including pair production of electroweakinos, sleptons, and top squarks. The search focuses on events with a high transverse momentum system from initial-state-radiation jets recoiling against a potential sparticle system with significant missing transverse momentum. Events are categorized based on their lepton multiplicity, jet multiplicity, number of b-tagged jets, and kinematic variables sensitive to the sparticle masses and mass splittings. The sensitivity extends to higher parent sparticle masses than previously probed at the LHC for production of pairs of electroweakinos, sleptons, and top squarks with mass spectra featuring small mass splittings (compressed mass spectra). The observed results demonstrate agreement with the predictions of the background-only model. Lower mass limits are set at 95% confidence level on production of pairs of electroweakinos, sleptons, and top squarks that extend to 325, 275, and 780 GeV, respectively, for the most favorable compressed mass regime cases.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.156121.v1/t1","@type":"Dataset","description":"Event counts observed in data, $N_{\\rm{obs}}$, in each of the model-independent bins, compared with predictions from the control region fit,...","name":"Table 11"},{"@id":"https://doi.org/10.17182/hepdata.156121.v1/t2","@type":"Dataset","description":"Top squark pair production.
