FCC Software

About

FCC Software provides a set of software packages, tools, and standards to help different FCC physics efforts work together. The software ecosystem of the FCC fully employs Key4hep stack and is one of its main stakeholders.

Signpost

The FCC Software ecosystem spans many sites, repositories and packages. The list of links bellow tries to offer a starting point.

All developments happen in github.com/HEP-FCC and github.com/key4hep. The best place to check for detailed information on a specific package thus is usually its homepage / Github repository page.

Getting Started

• FCC Tutorials: Tutorials on how to get started with FCC Software. Those tutorials are also used during the workshops.
• Key4hep Documentation: Growing documentation of the Key4hep and its components.
• FCC-ee Detector Full Sim: FCC-ee detectors implementation, simulation and reconstruction documentation
• FCC Software Glossary: A glossary of HEP and FCC-specific terms and concepts.
• ALEPH Documentation: Resurrecting ALEPH data in EDM4hep format (CERN log-in required).

Meeting People and Getting Help

• FCC Software Meetings: Indico category for FCC Software meetings.
• FCC Software Forum: Forum for questions related to FCC Software from Generators to Analysis.
