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 electron candidate was observed and missing energy implies to the presence of a neutrino. The data was selected from the primary dataset SingleElectron 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.

| delPhi | The difference in phi between the electron track and the associated cluster in the ECAL (rad). |
| 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. |
| 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 is was one electron in the event with pT > 25.0 GeV. Furthermore, the event was rejected if there was a second electron present with pT > 20 GeV.
How can you use these data?
