The Compact Muon Solenoid experiment (CMS) is one of the two "general purpose" detectors situated on the Large Hadron Collider (LHC) at CERN. Occupying a cathedral-sized cavern under the ground near Cessy, France, and weighing in at around 12,500 tonnes, it has been designed to probe the smallest constituents of matter in an effort to understand some of the most profound questions we can ask of Nature. Imperial College physicists were heavily involved in the design and construction of CMS, and continue to enjoy a leading role as the 3,300-strong CMS Collaboration extracts results from the LHC's countless particle collisions.

The Imperial College HEP group contributes to the CMS experiment in three major areas:

  • The detector: the equipment with which we make the measurements;
  • Computing: processing, storing and managing the measurement data, as well as generating simulated data to aid the analysis of our results;
  • Physics: interpreting the data to gain a deeper understanding of Nature.
