LOGS FOR V+JETS ANALYSIS

This page is supposed to be a logbook for our VJETS analysis and the related software development. All users are welcome to contribute.

ANALYSIS STRATEGY

  • Use particle flow reconstruction machinery alongwith PF2PAT tool in CMSSW.
  • Events triggered by suitable path are subjected to following chain:
    • Preselection: We apply =Scrapping Filter, HBHENoiseFilter
    • Run PF2PAT and store the interesting objects in local storage
    • Apply Z/W filter from DelPanj and store information from passing events in flat trees.
    • Further analysis can be done with flat trees.

THE DelPanj PACKAGE

This package started as a code for creating flat TTrees from the official CMS datafiles. It has three independent submodules:
  • TreeMaker: This include following facilities
    • eSelector
    • muSelector
    • ZeeFilter
    • ZmmFilter
    • EMuFilter (Used for estimation of ttbar backgrounds in the Z (ee/μμ) final states).
    • EventCounter
  • TreeMaker: We also have a wish-list for adding following facilities
    • jetSelector
    • WENuFilter
    • WMNuFilter
  • TreeAnalyzer: Simple macros for analysing the TTrees, Fitting and Unfolding
  • Scripts: Python scripts to perform certain functions like: submitting batchJobs at lxplus, killing your jobs, transferring from castor, cleaning castor etc.
