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
GBAR joins the anticlub
The GBAR experiment at CERN has just joined the very select club of experiments that have succeeded in synthesising antihydrogen atoms
ALICE shines light into the nucleus to probe its structure
New ALICE results shed light on the nature of gluonic matter at the LHC
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
SHINE shines a light on neutrino beams
The NA61 experiment at CERN, also known as SHINE, has made new measurements that will help physicists work out the content of neutrino beams used in experiments in the US
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
Probing fundamental symmetries of nature with the Higgs boson
The ATLAS collaboration tested Higgs-boson interactions with the carriers of the weak force, looking for signs of charge-parity symmetry violation
ALICE sees the ridge in simplest collisions yet
The observation brings physicists a step closer to finding the origin of collective phenomena in small collision systems
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.
