Dataset Derived Education CMS CERN-LHC Parent Dataset: Datasets derived from the Run2011A SingleElectron, SingleMu, DoubleElectron, and DoubleMu primary datasets
Description
This document contains 100k events where one muon candidate was observed and missing energy implies to the presence of a neutrino. The data was selected from the primary dataset SingleMu 2011. These data were selected for use in education and outreach and contain a subset of the total event information. They are not suitable for a full physics analysis.

| Variable | Description |
|---|---|
| Run | The run number of the event. |
| Event | The event number. |
| pt | The transverse momentum of the muon (GeV). |
| eta | The pseudorapidity of the muon. |
| phi | The phi angle of the muon (rad). |
| Q | The charge of the muon. |
| chiSq | The chi-squared per degree-of-freedom of the muon. |
| dxy | The impact parameter in the transverse plane with respect to the vertex of the muon. |
| iso | The combined isolation (Itrack + Iecal + Ihcal) of the muon. |
| MET | The missing transverse momentum of the event (GeV). |
| phiMET | The phi angle of the missing transverse momentum (rad). |
How were these data selected?
An event was selected if there was one (and only one) global muon in the event that satisfies: pT > 25.0 GeV and |eta| < 2.1. Furthermore, the event was rejected if there was another global muon in the event with pT > 10 GeV in the acceptance region |eta| < 2.4.
How can you use these data?
