Overview
Particle-physics data from the CERN Open Data Portal: collision, simulated and derived datasets, analysis software, environments and documentation from ALICE, ATLAS, CMS, LHCb and other experiments. Search it with exact-vocabulary filters and live facet counts, open records with their license and citation, list the files that hold the data, assemble a record's analysis environment, and look up CMS good-run lists and trigger paths. Runs as a stdio process or a local Streamable HTTP server.
