==This is the main page for the Herwig tutorial at the MCnet 2019 school.==
This is the tutorial for the first day of the MCnet school and 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 virtual docker image (see next section). If you plan to use Herwig for your own research after the MCnet school the instructions provided under [[ https://phab.hepforge.org/w/mcnet2019/installation/ | Installation ]] might be helpful.
Todo: check that everything works with the VM/Docker image
During the course of 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 containers.
If you have not already installed docker, please follow the instructions on the docker website and install docker on your personal computer.
The required docker container can be pulled directly from dockerhub with
docker pull hepstore/rivet-herwig
Thats basically it. 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 hepstore/rivet-herwig Herwig
This allows the container to access your local files and to write files to the current working directory.
Alternatively, you can create an alias with
alias Herwig ='docker run -i --rm -u `id -u $USER`:`id -g` -v $PWD:$PWD -w $PWD hepstore/rivet-herwig Herwig'
Now all you have to do to run Herwig is to execute
Herwig
in your terminal.
We also recommend to create an alias for the rivet command **rivet-mkhtml**
alias rivet-mkhtml ='docker run -i --rm -u `id -u $USER`:`id -g` -v $PWD:$PWD -w $PWD hepstore/rivet-herwig rivet-mkhtml'
If this works fine you are ready to start the tutorial with [[ https://phab.hepforge.org/w/mcnet2019/firstrun/ | First run: LEP]]. If not, talk to a tutor.
