Z to two electrons from 2011
McCauley, Thomas
Dataset Derived Education CMS CERN-LHC Parent Dataset: Datasets derived from the Run2011A SingleElectron, SingleMu, DoubleElectron, and DoubleMu primary datasets
Description
This document contains 10k events where two electron candidates with invariant mass near the mass of Z-boson were observed. The data was selected from the primary dataset DoubleElectron 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 electron (GeV). |
| eta | The pseudorapidity of the electron. |
| phi | The phi angle of the electron (rad). |
| Q | The charge of the electron. |
| type | Either EB or EE: whether the electron is in the barrel or in the endcap. |
| sigmaEtaEta | The weighted cluster rms along eta for an electron. |
| HoverE | The energy of the electron in the HCAL divided by the energy of the electron in the ECAL. |
| isoTrack | The isolation variable for the electron in the tracker. |
| isoEcal | The isolation variable for the electron in the ECAL. |
| isoHcal | The isolation variable for the electron in the HCAL. |
How were these data selected?
An event was selected if there were two electrons in the event with pT > 25 GeV and the invariant mass of the two electrons was > 60 GeV and < 120 GeV.
How can you use these data?
