Searches for supersymmetry in final states with leptons or photons and missing energy

TL;DR

This paper reports on searches for supersymmetry using CMS data at 7 TeV, focusing on final states with jets, missing energy, leptons, and photons, and interprets results within the CMSSM framework.

Contribution

First comprehensive search for supersymmetry in multiple final states with leptons and photons at 7 TeV LHC data, employing data-driven background estimation methods.

Findings

No significant excess observed over Standard Model predictions.

Constraints placed on supersymmetry parameter space within the CMSSM.

Methodology developed for background estimation in complex final states.

Abstract

We present the results of searches for Supersymmetry in various topologies that lead to final states with jets and missing transverse momentum together with one or more isolated leptons, one or two photons or a photon and a lepton. The searches are performed using data collected by the CMS experiment at the LHC in pp-collisions at a center-of-mass energy of 7 TeV. Various data- driven techniques used to measure the Standard Model backgrounds are discussed. The results are interpreted in the CMSSM framework.
