At CERN, we probe the fundamental structure of particles that make up everything around us. We do so using the world's largest and most complex scientific instruments.

The Higgs boson, as proposed within the Standard Model, is the simplest manifestation of the Brout-Englert-Higgs mechanism. It gives mass to elementary particles.
This search for exotic long-lived particles looks at the possibility of “dark photon” production, which would occur when a Higgs boson decays into muons displaced in the detector
New result from the ATLAS experiment at CERN reaches the unprecedented precision of 0.09%
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 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 decay width is linked to the particle’s lifetime and if found to deviate from its predicted value could indicate the presence of new physics
History teaches that those who explore relentlessly and fearlessly are often the ones rewarded with the greatest prize of all: the truth.
Since its discovery in 2012, the Higgs boson has become one of the most powerful tools to probe our understanding of nature and, with that, examine some of the biggest open questions in physics today.
The ATLAS and CMS collaborations have searched for matter–antimatter asymmetry in the interaction between the Higgs boson and the tau lepton
It was just a few short weeks in mid-2012, but they were so intense that it felt like years. As 4 July drew near, the ATLAS and CMS experiments could sense that they were homing in on something big.
On 10 September 2008, the LHC circulated its first beams. It may not have been all plain sailing from then on, but the adventure had begun.
