The Terascale alliance Monte Carlo school (Nov 24-28) at DESY Hamburg is designed for master/PhD students and young postdocs.

The tentative programme comprises lectures and a tutorial:
Lectures:
- Introduction (Hard scattering, matrix element, Parton showers, Sudakov form factor, underlying event (QCD radiation and MPI) and hadronization, weighting, integration, phase space, random numbers, veto,...) - Torbjörn Sjöstrand
- NLO and higher-order calculations - Rene Poncelet
- Parton shower matching/merging - Tomas Jezo
- Parton shower accuracy - Daniel Reichelt
- Resummation - Andrea Banfi
- Handling negative weights - Andreas Maier
- Parton distributioun functions - Katerina Lipka

During the hands-on tutorial you will learn how Monte Carlo methods can be applied.

The school fee covering breaks and one workshop dinner is 100 Euros.

5 Computing set-up

Please bring your laptop!

For the Pythia tutorials:
* A standard Unix terminal window, as available in Linux and MacOS.
This excludes Windows, unless you yourself know how to install and
operate with the Windows subsystem for Linux.
* Other standard tools, such as a text editor and web browser.
* A C++ compiler, accepting C++11 (or later) code.
* For nicer plotting preferably you should also have a Python 3
installation, including the Matplotlib library. If you have the
former but not the latter, run
python3 -m pip install -U matplotlib

For the Sherpa tutorials:
* Tutorials based on docker images. Suggest to install docker in advance: https://docs.docker.com/install
* to avoid having to download the docker image all at the same time it would be a good idea to download the image in advance with:
docker pull hepstore/rivet-sherpa:3.1.8
docker container run -it -v $PWD:$PWD -w $PWD hepstore/rivet-sherpa:3.1.8 /bin/bash
Sherpa --version
* If you'd like to work with a local Sherpa installation instead of docker, it is useful to install rivet suit from rivet-bootstrap in advance: https://gitlab.com/hepcedar/rivet/-/blob/release-3-1-x/doc/tutorials/installation.md#installation-1

For the Herwig tutorials:
* Tutorials based on docker images. Suggest to install docker in advance: https://docs.docker.com/install
* to avoid having to download the docker image all at the same time it would be a good idea to download the image in advance with: "docker pull herwigcollaboration/herwig-7.3:7.3.0" (where on Linux people will most likely need a "sudo" in front for this to work)

If you need any additional support (via DESY computing access), contact us.
