ATLAS sets record precision on Higgs boson’s mass
New result from the ATLAS experiment at CERN reaches the unprecedented precision of 0.09%
50 years of giant electroweak discoveries
On 19 July 1973, the Gargamelle bubble chamber at CERN revealed the existence of weak neutral currents and put the nascent Standard Model of particle physics on solid ground
LHCb tightens precision on key measurements of matter–antimatter asymmetry
The LHCb collaboration’s new measurements of matter–antimatter asymmetry in decays of beauty particles are the most precise yet of their kind
LHC experiments see first evidence of a rare Higgs boson decay
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
ISOLDE takes a solid tick forward towards a nuclear clock
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
Where does the Higgs boson come from?
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.
New LHC experiments enter uncharted territory
The first observation of collider neutrinos at the LHC paves the way for exploring new physics scenarios
Celebrating the International Day of Women and Girls in Science
On 11 February 2023, we acknowledge the valuable contributions of women and girls to science, technology, engineering and mathematics
W boson turns 40
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
ATLAS delivers most precise luminosity measurement at the LHC
Precise knowledge of luminosity is crucial for both searches for new phenomena and precision measurements of known Standard Model processes
