The CMS 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 and data collected by CMS are shared with several computing centres via the Worldwide LHC Computing Grid. From there, they are distributed to over 4000 particle physicists, engineers, computer scientists, technicians and students from over 240 institutes and more than 50 countries.

The CMS Collaboration has an active outreach and science communication effort, targeting diverse audiences from primary school students through stakeholders at for example funding agencies. The CMS collaboration at the CERN LHC has made substantial datasets of open data available to the public, including large parts of the data which formed the basis for the discovery of the Higgs boson. These data are also used in the CMS contribution to the IPPOG International Physics Masterclasses. It is possible to visit the CMS detector virtually and in person
