Search for supersymmetry in single lepton events with the full Run 2 data — •Frederic Engelke^4,5, Kerstin Borras^4,5, Kimmo Kallonen³, Henning Kirschenmann³, Pantelis Kontaxis¹, Dirk Krücker⁴, Isabell Melzer-Pellmann⁴, Ashraf Mohammed^4,5, Paris Sphicas^1,2, Costas Vellidis¹, and Lucas Wiens⁴ — ¹University of Athens — ²CERN — ³Helsinki Institute of Physics — ⁴DESY — ⁵RWTH Aachen IIIA

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.

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.

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.
