Y to two muons from 2011

Dataset Derived Education CMS CERN-LHC Parent Dataset: Datasets derived from the Run2011A SingleElectron, SingleMu, DoubleElectron, and DoubleMu primary datasets
Description
This document contains 20k events where two muon candidates with invariant mass near the mass of upsilon were observed. The data was selected from the primary dataset DoubleMu 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. |
| type | Either T or G: whether the muon is a tracker or global muon. |
| E | The total energy of the muon (GeV). |
| px,py,pz | The components of the momemtum of the muon (GeV). |
| 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. |
How were these data selected?
An event was selected if there were two muons in the event, both with |eta| < 2.4, at least one muon was a global muon, the invariant mass of the two muons was > 8 GeV and < 12 GeV, and they have opposite-sign charge.
How can you use these data?
Comma-separated value (csv) files can be used in online applications such as the histogram visualizer and other applications, examples are given in
