The Discovery Potential of Supersymmetry at CMS within the mSUGRA Model Using Same-Sign Di-Muons

TL;DR

This paper investigates the potential for discovering supersymmetry at CMS using same-sign di-muon signatures within the mSUGRA model, demonstrating significant detection prospects with current collider data.

Contribution

It provides a detailed analysis of the same-sign muon signature in the mSUGRA model, identifying conditions under which SUSY signals could be distinguished from background.

Findings

Potential to observe SUSY with less than 10 fb^-1 of data

Significant excess over Standard Model background at certain benchmark points

Sensitivity extends up to m_1/2 of 650 GeV/c^2

Abstract

A detailed study of the same-sign muon signature within the mSUGRA model is described. Selection criteria based on the missing transverse energy in the events and the jet and muon transverse momenta are applied. The results indicate that an excess of SUSY events over the Standard Model background processes can be statistically significant for an integrated luminosity of less than 10 fb^-1 for many benchmark points with m_1/2 up to 650 GeV/c^2.
