CERN Accelerating science

The ATLAS and CMS collaborations have joined forces to establish the first evidence of the rare decay of the Higgs boson into a Z boson and a photon

The observation at CERN’s nuclear physics facility of a long-sought decay of the thorium-229 nucleus in a solid-state system is a key step towards a clock that could outclass today’s most precise atomic clocks

The observed mass of the Higgs boson is, from the theoretical point of view, unnaturally small. This conundrum is forcing physicists to explore exotic explanations.

The first observation of collider neutrinos at the LHC paves the way for exploring new physics scenarios

On 11 February 2023, we acknowledge the valuable contributions of women and girls to science, technology, engineering and mathematics

Precise knowledge of luminosity is crucial for both searches for new phenomena and precision measurements of known Standard Model processes

Forty years ago today, physicists at CERN announced to the world that they had discovered the electrically charged carrier of the weak force, one of nature’s four fundamental forces

CMS has now released the complete set of proton-proton data taken from LHC Run 1, including the original findings used in the Higgs boson discovery

The LHCb collaboration has released data from Run 1 of the LHC to the public for the first time, allowing research to be conducted by anyone in the world
