Dependencies

• GCC

  We will be using GCC-4.9.1 for this project¹.
  If you are on lxplus, you can get it by sourcing

  source /cvmfs/sft.cern.ch/lcg/external/gcc/4.9.1/x86_64-slc6-gcc48-opt/setup.csh
  

• ROOT

  We will be using ROOT-6.06/06 for this project.
  If you are on lxplus, you can get it by sourcing

  source source /cvmfs/sft.cern.ch/lcg/releases/ROOT/6.06.06-5e975/x86_64-slc6-gcc49-opt/bin/thisroot.csh
  

• LHAPDF

  This analysis uses LHAPDF-6.1.2 which has been installed in the $HOME directory.
  It is needed for compiling and running main.x in ./hhDilep_pseudoanasol/

  gmake clean && gmake main.x && ./main.x 
  

  You can install LHAPDF-6.1.2 by running

  source /bin/installLHAPDF-6.1.2.csh     
  

• Delphes

  In order to run the Selection.C root script and installation of Delphes-3.4.0 in the $HOME directory is needed. You can install it by running

  source /bin/installDelphes-3.4.0.csh 
  

  For me, it works with ROOT 6.06/06 and gcc 4.9.1 which I load form lxplus.
  If you are not on lxplus, it should work by just downloading these versions on your local machine
  and editing the appropriate lines in DelphesEnv.csh and installDelphes.csh

Analysis Workflow

Due to the relatively large phase-space scan of main.x, the analysis takes quite a bit of time to run on a single machine. That's why we rely on HTCondor's resources to allow us to use parallel processing by submitting multiple jobs at a time.
If you want to study a certain PHYSICS_PROCESS = (pptohh, ttbar1, pptoohhsm, etc...) run

source create_jobs.csh pptohhsm
source submit_jobs.csh pptohhsm

if PHYSICS_PROCESS = pptohhsm. Else, change it accordingly.
A full list of the available PHYSICS_PROCESS is in physics_processes.txt

After the jobs finish running, use

root -l -b code/createHistos.C'("pptohhsm")'

to create histograms for the process pptohhsm.

Footnotes

1. Except for when we are compiling LHAPDF, where we will use 4.7, but this process is essentially outside the project. ↩
