This tutorial teaches you the basics of the Monte Carlo Event Generator Herwig. An installation of Herwig on your own device is not necessary if you use the provided docker image (see next section). If you plan to use Herwig for your own research follow the instructions provided under Installation .

In this tutorial you will learn:

How to simulate LEP events
How to simulate LHC events
How to include rivet analyses and compare simulation with data
How to switch parts of the Event Generator on and off
How to modify parameters of the Parton shower and the Hadronization model
The Les Houches Event Handler

Before you start (docker containers)

All exercises within this tutorial can be done by using the provided docker image for Herwig.
If you have not already installed docker, please follow the instructions on the docker website and install docker on your device.

The required docker containers can be pulled directly from the docker hub with

docker pull herwigcollaboration/herwig-7.3:7.3.0

Linux users: sudo docker ...

In order to run Herwig, execute the following shell command

docker run -i --rm -u `id -u $USER`:`id -g` -v $PWD:$PWD -w $PWD herwigcollaboration/herwig-7.3:7.3.0 Herwig --help

This allows the container to access your local files and to write to the current working directory

Create an alias for the run command with

alias DRH='docker run -i --rm -u `id -u $USER`:`id -g` -v $PWD:$PWD -w $PWD herwigcollaboration/herwig-7.3:7.3.0'

To run Herwig execute

DRH Herwig

Similar commands like rivet-mkhtml can be run in the same fashion

DRH rivet-mkhtml

If this works, you are ready to start the tutorial with First run: LEP. If you encounter problems, please talk to a tutor.

Instructions:

1. Installation
2. First run: LEP
3. Second run: Z production and jets at the LHC
4. Third run: minimum bias events and soft physics
5. The Les Houches Event Handler
