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.
