===== Dijet Jet Energy Resolution =====

This is my Qualification Task for ATLAS. \\
The progress is tracked on JIRA: https://its.cern.ch/jira/browse/ATLJETMET-765

===== Jets for Higgs Analyses =====

Look at jet performance for for the Higgs to diphoton analyses.

  - Monte-Carlo based & in-situ jet energy scale calibration & resolution measurements.
  - Investigation of topological-cluster & particle-flow jet input algorithms.

==== Work setup ====

The work-in-progress code is HGamJetStudy, a RootCore package for two studies:

  - ''MCJESR'' : Monte-Carlo based jet energy scale & resolution.
  - ''YYJetInSituJESR'' : (experimental) yy+jet in-situ jet energy scale & resolution.

The outputs are used to give us results (pretty plots):

  - ''MCJES -> plotJES'' (working)
  - ''MCJES -> plotJER'' (to do)
  - ''YYJetInSituJESR -> plotYYJetInSituJESR'' (working)

Full code and instructions are hosted on GitLab: https://gitlab.cern.ch/tapark/HGamJetStudy
