Fake Isolated Muon Background in Searches for Supersymmetry with two Muons in the Final State
2010 (English)Report (Other academic)
We study a data-driven technique to derive the contamination from fake isolated muons in a search for supersymmetric (SUSY) particles, in final states with two high pT muons. The signal sample is characterized by jets, missing transverse energy and two high pT muons, isolated from calorimeter energy. In real data, a fraction of the selected events will arise from processes where at least one of the isolated muons is not truly isolated, but rather arises in conjunction with a jet. We illustrate how to determine the contribution from fake isolated muons, to the signal sample. The method is demonstrated with a simple SUSY analysis of the di-muon sample. We study a range of potential systematic effects arising from the extrapolation from the control sample to the signal region.
