FCCAnalyses

Common framework for FCC related analyses. This framework allows one to write full analysis, taking EDM4hep input ROOT files and producing the plots.

Quick start

Running analysis script can be done using fccanalysis command which is shipped in Key4hep stack:

source /cvmfs/sw.hsf.org/key4hep/setup.sh
fccanalysis run analysis_script.py

To have access to the FCC pre-generated samples, one needs to be subscribed to one of the following e-groups (with owner approval) fcc-eos-read-xx with xx = ee,hh,eh.

Detailed documentation can be found at the FCCAnalyses webpage.

Running over pre-generated samples

In order to run over pre-generated samples from winter2023 or spring2021 campaigns one needs to use release v0.9.0 of FCCAnalyses:

• Nightlies:

  source /cvmfs/sw-nightlies.hsf.org/key4hep/setup.sh -r 2024-02-21
  git clone --branch v0.9.0 [email protected]:HEP-FCC/FCCAnalyses.git
  cd FCCAnalyses
  source ./setup.sh
  fccanalysis build -j 8
  

• Stable stack:

  git clone --branch v0.9.0 [email protected]:HEP-FCC/FCCAnalyses.git
  cd FCCAnalyses
  source ./setup.sh
  fccanalysis build -j 8
  

Pre-generated Samples

All sample information, including Key4hep stack used for the campaign, is collected at the FCC Physics Events website.

Contributing

As usual, if you aim at contributing to the repository, please fork it, develop your feature/analysis and submit a pull requests.

Code formating

The preferred style of the C++ code in the FCCAnalyses is LLVM which is checked by CI job.

To apply formatting to a given file:

clang-format -i -style=file /path/to/file.cpp
