CERN Accelerating science

Fabiola Gianotti, CERN Director-General, was spokesperson of the ATLAS experiment at the Large Hadron Collider from 2009 to 2013 and responsible for announcing the discovery of the Higgs boson, alongside the CMS spokesperson

The ATLAS experiment at the LHC reveals how pairs of top quarks are produced along with other heavy quarks

Using data from the first heavy-ion run of LHC Run 3 in 2023, the experiment presents the first-ever measurement of D0 meson production in photon-lead collisions

The aim of the third update of the European Strategy for Particle Physics is to develop a visionary and concrete plan that greatly advances human knowledge in fundamental physics through the realisation of the next flagship project at CERN

With new measurements of hadron–deuteron correlations, the ALICE collaboration explores the strong interaction of three-body systems at the LHC.

In the Standard Model of particle physics, the odds of this decay occurring are less than one in 10 billion

With its updated analysis methods, the ATLAS collaboration has significantly improved the precision of its measurements of Higgs boson interactions

The eagerly awaited result is the most precise measurement of the W mass made at the LHC so far, and is in line with the prediction from the Standard Model of particle physics
