A toy parton shower for educational purposes.

Pre-requisites:

1. python 3.x
2. pyhepmc
3. matplotlib, numpy, scipy.

Usage:

There are three main files in this tutorial:

1. The "test" code, providing a basic demonstration of the parton shower sudakov veto algorithm:

python3 pyresias_test.py -n [Number of Branches] -Q [Starting scale] -c
[Cutoff Scale] -o [outputdirectory] -d [enable debugging output]

2. The JupyterLab notebook jupyter_nb.ipynb, which includes a step-by-step guide of the above "test" code:

3. The parton shower on $e^+ e^- \rightarrow q\bar{q}$ LHE files:

python3 pyresias.py data/LHE_FILE.lhe.gz

An example LHE file is provided in the "data" directory, generated through MadGraph5_aMC@NLO.
