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 ...

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 result, from the CMS experiment at the Large Hadron Collider (LHC), is in line with the predictions of the standard model of particle physics, and pours cold water on an anomaly in the W boson ...
