An unforeseen feature in proton-proton collisions previously observed by the CMS experiment at CERN's Large Hadron Collider ...

Scientists at CERN have observed an unexpected phenomenon within the world’s largest particle accelerator that suggests that ...

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 ...

Scientists from CERN have measured the speed of sound in the quark-gluon plasmas with record precision, a key step to ...

Learn about the Compact Muon Solenoid (CMS) experiment at CERN's Large Hadron Collider, including its purpose, design and achievements.

Physicists at CMS are trying to change that. Like particles produced in other experiments at CERN, the hypothetical dark photons would be produced by the decay of another particle: the Higgs boson ...

Cms magnet is the result of a large international collaboration among Italian Institute of Nuclear Physics, Cern, Commissariat pour l'Energie Atomic (Cea) in Saclay (France) the Eth-Z (Polytechnic ...

Aug. 28, 2020 — The CMS collaboration at CERN has released into the open 18 new datasets, comprising proton–proton collision data recorded by CMS at the Large Hadron Collider (LHC) during the second ...

When I began working on CMS as a CERN fellow back in 1994, the LHC and its experiments were expected to operate for about 15 years, starting from around 2005. However, CERN’s decision to upgrade the ...

The Large Hadron Collider at CERN is the world's largest and most expensive particle accelerator. Two teams of about 3,000 physicists each — one named Atlas and the other CMS — operate giant ...

Earlier today, physicists and engineers at CERN replaced the heart of the Compact Muon Solenoid (external page CMS) experiment, one of the two general purpose particle physics detectors that ...
