Performance of Jet Finding

General Information

Tools and procedure

Using HID root file that contains CaloJet? reconstruction data which was reconstructed and converted in CMSSW, It was possible to access reconstructed jet data from HIROOT. There are mixed and unmixed MC information in same root file, so It was also possible to run jet finding module on that information.

Naming Rule

HR Gen Part Jet : Jets from MC particle information
CS Reco Calo Jet : Reconstructed jets from calorimeter information in CMSSW

HR Gen Part Jet vs CS Reco Calo Jet

Condition 1 : Using Only Signal Record

HR Gen Part Jet - Iterative Cone Finder
- Seed threshold : 2/5/10 GeV?
- Jet threshold : 30 GeV?
- use only one signal record in one event.
