CERN Accelerating science

The collaboration’s latest study of a “strange”, unstable nucleus known as the hypertriton offers new insight into the particle interactions that may take place at the hearts of neutron stars

History teaches that those who explore relentlessly and fearlessly are often the ones rewarded with the greatest prize of all: the truth.

Using LHC Run 2 data, CMS has precisely measured the rare decay of strange B-mesons to muon-antimuon pairs. While its properties agree with Standard Model predictions, it may provide clues to new discoveries in Run 3

Joint-polarisation measurements of the W and Z bosons provide new opportunities to look for physics beyond the Standard Model

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.

The collaboration has observed a new kind of “pentaquark” and the first-ever pair of “tetraquarks”
