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 ATLAS collaboration tested Higgs-boson interactions with the carriers of the weak force, looking for signs of charge-parity symmetry violation

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

The observation brings physicists a step closer to finding the origin of collective phenomena in small collision systems

The ATLAS and CMS collaborations have both observed the simultaneous production of four top quarks, a rare phenomenon that could hold the key to physics beyond the Standard Model

Registrations are now open for this conference, which will be held virtually with India as the host country

An improved ATLAS measurement of the W boson mass is in line with the Standard Model of particle physics
