The Large Hadron Collider at CERN is the world’s largest and most powerful particle accelerator, representing a landmark achievement in large-scale international scientific collaboration. Over 10,000 scientists and engineers from more than 100 countries participate in experiments conducted at the facility, organized into major collaborations such as ATLAS and CMS. The project required developing new models for distributed computing, shared governance, and consensus-based decision-making at an unprecedented scale. CERN is also the birthplace of the World Wide Web, which was invented to facilitate information sharing among the geographically dispersed physics community, and later gave rise to the Worldwide LHC Computing Grid for distributed data processing. It is particularly relevant in Environmental Science, Software Engineering and Public Policy.

CERN Large Hadron Collider supports interdisciplinary, distributed and co-production collaboration and is suited for multi-organization networks and community-scale initiatives in in-person, remote and hybrid settings.

CERN Large Hadron Collider is classified as a well-documented case study, indicating broad adoption and available documentation. This case study examines the collaborative practices at CERN, drawing on experiences since 2008.
