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.
|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.|
|delEta||The difference in eta between the electron track and the associated cluster in the ECAL (rad).|
|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).|
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.
