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

The collaborations have used the largest samples of proton–proton collision data recorded so far by the experiments to study the unique particle in unprecedented detail

The discovery of the Higgs boson at the Large Hadron Collider and the progress made since then, have allowed physicists to make tremendous steps forward in our understanding of the universe

The Large Hadron Collider is ready to once again start delivering proton collisions to experiments, this time at an unprecedented energy of 13.6 TeV, marking the start of the accelerator’s third run of data taking for physics

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.

What’s so special about the Higgs boson? Why should I care? What’s next? If these questions torment you, head straight to home.cern.

How can we support members of our Laboratory in addressing conflict early on, before it reaches the Ombud’s Office?
