Some Important Commands

  1. edmDump
    • edmDumpContent
      • edmDumpContent abc.root
      • edmDumpContent --all --regex muon abc.root # This will show only those lines that contains muons
    • edmEventSize
      • edmEventSize -v abc.root
      • edmEventSize -o file.txt file.root # This will send output to the file.txt

Important Variables To Plot

Various Cuts applied in my Analysis and their significance


Standard physics objects/ID/algorithm


  • explain what are the standard objects id and/or algorithm accepted by your group

Algorithms for something else

  • link to a doc page - short explanation

Analysis Progress

  1. Generation of MadGraph Sample
    1. Generation of pp > wwjj : done for all But It contains many feynman Diagram that does not corresponds to the WW scattering diagram
    2. Decay using MadSpin : Done only for:
      PDF used nn23lo1
      1. pp_WWJJ_TOT/Default_Cut : both wpHad and WpLep
      2. pp_WWJJ_LL/Default_Cut/ : both wpHad and wpLep
      3. pp_WWJJ_LT/Default_Cut/ : both wpHad and wpLep
      4. pp_WWJJ_TT/Default_Cut/ : both wpHad and WpLep

      5. pp_WWJJ_LL/NoPtEtaCut/ :
  2. Read LHE file : Code Ready
  3. GEN-SIM Stage running interactively; But Crab3 job is not running.
To extract lhe.gz file use command : gunzip -f filename.lhe.gz
