The CMS Collaboration brings together members of the particle physics community from across the globe in a quest to advance humanity’s knowledge of the very basic laws of our Universe. CMS has over 4000 particle physicists, engineers, computer scientists, technicians and students from around 240 institutes and universities from more than 50 countries.

The collaboration operates and collects data from the Compact Muon Solenoid, one of the general-purpose particle detectors at CERN’s Large Hadron Collider. Collaborators from all over the world helped design and fabricate components of the detector, which were brought to CERN for final assembly. Data collected by CMS are shared with several computing centres via the Worldwide LHC Computing Grid. From there, they are distributed to CMS institutions in over forty countries for physics analysis.

In keeping with CERN’s commitment to open access for high-energy physics, the scientific results from CMS are shared openly with the world.
