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.
|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).|
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.
