Tracking Efficiency

The following plots/tables use these track selection cuts: truth pT > 0.5 GeV and truth production (R < 150 mm and |z| < 400 mm) and truth |eta| < 2.5. A matching probability of at least 0.8 is required.

  • Efficiency as a function of pT:

  • Efficiency as a function of |eta|:

  • Efficiency as a function of D0:

  • Integrated tracking efficiencies
CombinedInDetTracks : total eff. rate = 6.807e-01 +- 1.776e-02
SiSPSeededBeamGasTracks : total eff. rate = 7.286e-01 +- 1.694e-02

Tracking Fake Rates

The following plots/tables use these track selection cuts: reco pT > 0.5 GeV and reco |eta| < 2.5.

  • Fake rate as a function of pT:

  • Integrated tracking Fake rates
-- classical fakes (with association)
 CombinedInDetTracks : total fake rate = 8.042e-04 +- 4.019e-04
SiSPSeededBeamGasTracks : total fake rate = 3.432e-04 +- 9.905e-05
-- no link (association)
 CombinedInDetTracks : total no link rate = 8.842e-01 +- 4.537e-03
SiSPSeededBeamGasTracks : total no link rate = 9.675e-01 +- 9.485e-04
