Search for supersymmetry in final states with opposite-sign same-flavor lepton pairs at the CMS experiment with data taken from 2016 to 2018 — Lutz Feld, Danilo Meuser, Johannes Schulz, and •Marius Teroerde — 1. Physikalisches Institut B, RWTH Aachen

Supersymmetry (SUSY) is an extension of the standard model (SM) of particle physics with the potential to solve open questions in physics like the unification of forces or the nature of dark matter by introducing superpartners to all SM particles. In the presented analysis, the production of opposite-charge same-flavor lepton pairs along with jets and stable, undetected SUSY particles is considered.

Events from top-pair production have a similar event topology and thus are an important background to the analysis. A likelihood variable based on the characteristics of top-pair production suppresses this background. Using the flavor-symmetry of the process, a data-driven background estimation is then employed.

The presented search is performed on data taken by the CMS detector at the Large Hadron Collider at √s=13 TeV in the years 2016 to 2018.
