A Supersymmetry search strategy with single-lepton events at 13 TeV by the CMS experimentArtur Lobanov, Claudia Seitz, Isabell Melzer-Pellmann, and •Akshansh Singh — DESY, Hamburg, Germany

We present an inclusive search for supersymmetry in the single-lepton channel with 13 TeV. To optimise the sensitivity to various new-physics topologies, we search in several exclusive categories which differ in the number of jets and b-tagged jets. We determine the background from data, exploiting the fact that the main background is located at small values of the azimuthal angle between the W-boson candidate and the charged lepton. To be less dependent on the new-physics scale, we also introduce separate search categories based on the scalar sum of the jet transverse momenta and on the scalar sum of the transverse missing momentum and the transverse momentum of the lepton. Depending on the signal model, the signals regions have varying sensitivity. Here we concentrate on gluino-gluino production, where the pair-produced gluinos decay to a top-antitop pair and the lightest neutralino
