Introduction

Analysis Code

The HiggsSelfCouplings package contains classes to build objects, to apply selection cuts and to implement the smearing, efficiency and fake-rate functions defined in the TruthToRecoFunctions package to parameterise the detector performance under HL-LHC conditions.

You can browse the code in:

WebSVN: https://svnweb.cern.ch/cern/wsvn/atlas-cbarrera

or in:

Trac: https://svnweb.cern.ch/trac/atlas-cbarrera/browser

Instructions

To help setting-up athena, add the following line to your .bashrc file:

alias asetup17 = 'source /data/atlas09/ferrando/atlas_soft/17.2.2/AtlasSetup/scripts/asetup.sh 17.2.2.2' 

Now exit the terminal and open a fresh window.

First you need to get the code from SVN:

export SVNUSR=svn+ssh://<cern_username>@svn.cern.ch/reps/atlas-cbarrera
svn co $SVNUSR/HiggsSelfCouplings/trunk HiggsSelfCouplings

The first time you use the package you need to run the script called setup_firsttime.sh, which sets up athena and updates the files inside RootCore so that they point to the correct directories:

cd HiggsSelfCouplings
source setup_firsttime.sh

This you need to do only once. Everytime you want to run the code, you just need to setup athena and RootCore by doing:

cd HiggsSelfCouplings
asetup17
source packages/RootCore/scripts/setup.sh

To compile the code, just do:

make

This creates an executable file which you can run as:

./mainHHAnalysis
