Search for Supersymmetry in final states with two opposite-sign same-flavor leptons, jets, and ETmiss in pp collisions at √s=13 TeV with the CMS experiment — Christian Autermann, Lutz Feld, •Christian Schomakers, and Jan-Frederik Schulte — 1. Physikalisches Institut B, RWTH Aachen University
One of the main purposes of the LHC is the search for new physics which is predicted by theories such as Supersymmetry (SUSY) and is necessary to solve several problems of the standard model. Cascade decays of SUSY particles often yield final states with hadronic activity and missing transverse energy. Signatures including leptons are of particular interest since standard model background processes are suppressed by this selection and can be predicted with good accuracy.
The invariant dilepton mass distribution can provide further information on possible decays of SUSY particles. At 8 TeV, CMS observed an excess of 2.6 σ at a low dilepton mass. ATLAS did not confirm this deviation but reported an excess of 3.0 σ in a nearby signal region on the Z-peak.
The CMS SUSY dilepton search was repeated at 13 TeV and the results are presented.
