First steps towards leptonic SUSY searches with 13 TeV LHC data

This project report is on the first steps of leptonic SUSY searches with the first 13 TeV LHC data. The first inverse picobarns of data collected with the CMS detector during the summer of 2015 enables for a reconstruction of several benchmark standard model processes. For leptonic SUSY searches, control regions can be defined to study processes with leptonic final states. The aim of this project is to define and reconstruct the control regions with the available data, for prompt and fake leptons, and to derive an inclusive scale factor for the efficiency of a susy-like selection on processes with prompt leptons (signal & SM rare backgrounds) and non-prompt ones (reducible background). The plots presented in this report is a subset of plots that have been approved for EPS1 and a part of a Detector Performance Summary2.
