Quick Start

As a user, clone the repo over https using:

git clone --recursive https://github.com/LukeV37/Pileup_Project.git

As a developer, clone the repo over ssh using:

git clone --recursive git@github.com:LukeV37/Pileup_Project.git

Ensure dependencies are installed (see below), and build the submodules:

./build_submodules.sh

Please be patient while submodules build...

See software/README.md for more information regarding submodules.

How To Generate Datasets

First, generate events in MadGraph:

cd madgraph
# Generate Signal
./run_dihiggs.sh
# Generate Background
./run_4b.sh

For more information on pythia, please see madgraph/README.md.

Then, shower in Pythia8:

cd pythia
./generate_diHiggs.sh {diHiggs|4b} {mu} {String Modifier} {MinJetpT}

The root file generated by the pythia simulation will be found in pythia/output.

For more information on pythia, please see pythia/README.md.

Dependencies

Tested on Ubuntu 22.04, EL9 lxplus machine, and even WSL2.

Required Dependencies:

• python3
• ROOTv6
• autoconf
• libtool
• automake
• tcl
• gfortran
• g++

ROOTv6 can be installed following instructions here.

Other packages can be intalled with sudo apt install {package}

Misc.

Warning

ROOT must be installed on the system before ./install.sh script can be run.
Use root-config --cflags --libs to see if you have a successful ROOT install.

Note

On GPURIG2, please add the following lines to your .bashrc file in your home directory:

export ROOTSYS=/usr/local/rootpy27/root_install
export PATH=$ROOTSYS/bin:$PATH
