Discoveries from the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland, are revolutionizing our understanding of the universe. More than 900 scientists from 50 institutions in the U.S. participate in the U.S. CMS collaboration, supported by the Department of Energy and National Science Foundation.

U.S. CMS consists of more than 400 physicists, 200 graduate students, and 200 engineers, technicians, and computer scientists, making it the largest national group in the international collaboration. The U.S. collaboration is making significant contributions to nearly every aspect of the detector throughout all phases, including construction, installation, and data-taking. U.S. CMS also plays a major role in the construction and operation of the experiment's computing facilities and software that is used to analyze the unprecedented amount of data that CMS generates. These highly sophisticated computing tools allow physicists to operate the CMS detector, reconstruct the data, analyze it and, ultimately, make discoveries.

The observation of a new particle, with properties consistent with those of the Higgs boson, was announced on July 4th, 2012.
