Jet Identification 

Mail: D0JET@fnal.gov
Convenor: Xuebing Bu
JetID Team: Yuji Enari, Dikai Li, Jeongku Lim.
Previous Convenors: Murilo Rangel and Thibault Guillemin

The jet IDs are implemented in JetSelector processor for CAFe

1. General jet selection:
(good jet and EM removal => isGood(), !isEM())
2. Vertex confirmation:
(with at least 2 associated tracks from primary vertex => ntrkMultiplicity0()>=2)

Using JetController to select jets in CAFe

Data

1. Apply certified JES with ApplyJES processor
2. Recalculate the EM removal flag
3. Select jets with JetSelector processor

MC

1. Apply certified JES with ApplyJES processor
2. Apply JSSR (shifting, smearing and removing) with RunJetSSR processor
3. Apply jet ID efficiency correction with JetCorr processor
4. Recalculate the EM removal flag
5. Select jets with JetSelector processor
