Results are presented from a search for supersymmetry in events with a single electron or muon, and multiple hadronic jets. The data corresponds to a sample of proton-proton collisions at √s=13 TeV with an integrated luminosity of 138 fb−1, recorded by the CMS experiment at the LHC.
The search targets gluino pair production, where the gluinos decay into the lightest supersymmetric particle (LSP) and either a top quark-antiquark pair or a pair of light quarks in the final state.
We use the angular correlation between the lepton and the W boson’s transverse momenta for a strong separation between the signal and the background region. The investigation of the two different signal models benefits from improved top and W tagging methods.
Furthermore, we also present current endeavors to prepare this analysis for the Run3 period using modern analysis tools.
