GDR-InF lectures on common analysis techniques in flavour physics

Some hands-on exercices complement the lectures. They will be available as Jupyter notebooks attached to the indico agenda. These notebooks can be run locally or in Google Colab. Running locally is the preferred option

Setup to run the notebooks locally

To run the notebooks locally you need to install ROOT, the easiest way is with miniforge:

Install ROOT (do be done once)

Install miniforge

wget -O miniforge.sh "https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-$(uname)-$(uname -m).sh"
bash miniforge.sh -b -p $HOME/miniforge
rm miniforge.sh
source $HOME/miniforge/bin/activate

Create a new environment with ROOT and a few other useful python packages

mamba create -y -n r root=6.28.04
source activate r
mamba install -y seaborn uncertainties jupyterlab scikit-hep xgboost

MacOS specific instructions (optional)

In some versions of macOS, you may encounter an error of this type: dyld: Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib when trying to isntall miniforge.
In this case, you can follow the following instructions (taken from
here):

First, install openssl@1.0

brew install rbenv/tap/openssl@1.0

Depending on your exact system configuration, you may need to switch to a different version. Check the output of ls -al /usr/local/Cellar/openssl for the version number to switch to.

Then

ln -sfn /usr/local/Cellar/openssl@1.0/<version> /usr/local/opt/openssl

Download the data and MC ntuples needed fot the exercices

Setup the environment (to be done each time)

source $HOME/miniforge/bin/activate
source activate r

Setup to run the notebooks in Google Colab
