The CMS experiment at CERN is the latest to weigh in on the mass of the W boson—an elementary particle that, along with the Z boson, mediates the weak force, which is responsible for a form of ...

The CMS Collaboration is working to constrain the parameters at which that process would occur. CERN’s Large Hadron Collider began its third run in July 2022, with a greater capacity for ...

National Institute for Nuclear Physics (INFN) The first module of the five constituting the CMS superconducting magnet is sailing on January 21st from Genova port to Cern.

Since the 1960s, scientists have discovered more than a dozen fundamental particles. They all have fit perfectly into the theoretical framework known as the Standard Model, the best description ...

The CMS experiment includes more than 4,500 particle physicists, engineers, computer scientists, technicians and students from more than 50 countries, according to its website.

The group has played a key role in constructing one of four major experiments now in place — the Compact Muon Solenoid (CMS), a complex array of instruments for detecting subatomic particles.
