1.Ntuple Variables & GEANT files

  • Location: Most files have been transferred on d02ka (B-project Disk):

    /prj_root/786/mub_3/RunIIB/lucotte/
    (See the specific directory in Section: 2. Dijet, 3.single electron, ... )

  • N-tuple definition: overall variables

  • Variables for the FPS: definition
  • Variables for the CPS: old & new variables definition
  • Current area of GEANT files:geant_files
  • There is a backup of (most of) the GEANT files:
  • Tape label: FPS_1C
  • Tape label: FPS_1D
  • 
    

    2. Di-jets production
