SUSY Searches with Leptons in the Final State at CMS

TL;DR

This paper reports on CMS searches for Supersymmetry using final states with leptons, analyzing 1 fb^{-1} of 7 TeV collision data from 2011, aiming to identify potential SUSY signals amid Standard Model backgrounds.

Contribution

First CMS search results for SUSY in leptonic final states at 7 TeV using 1 fb^{-1} of data, focusing on scenarios like CMSSM with reduced QCD background.

Findings

No significant excess observed over Standard Model predictions.

Constraints placed on SUSY parameter space based on the data.

Method demonstrates effective background suppression using lepton isolation.

Abstract

Recent results of the searches for Supersymmetry in final states with one or two leptons at CMS are presented. Many Supersymmetry scenarios, including the Constrained Minimal Supersymmetric extension of the Standard Model (CMSSM), predict a substantial amount of events containing leptons, while the largest fraction of Standard Model background events -- which are QCD interactions -- gets strongly reduced by requiring isolated leptons. The analyzed data was taken in 2011 and corresponds to an integrated luminosity of approximately $\mathcal{L} = 1\,\text{fb}^{-1}$. The center-of-mass energy of the pp collisions was $\sqrt{s}=7\,\text{TeV}$.
