The result opens a new window into the study of the quark–gluon plasma that is believed to have filled the Universe briefly after the Big Bang

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

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

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

The experiment has developed a new device for cooling antiprotons more efficiently and for considerably increasing the precision of measurements of their fundamental properties

Important information and key dates for the 2024-26 update of the European Strategy for Particle Physics

The ATLAS collaboration has released its first results from searches for new physics phenomena conducted with data from Run 3 of the LHC

The rarest hyperon decay ever observed

Re-analysing LHC Run 2 data with cutting-edge analysis techniques allowed CMS physicists to address an old discrepancy

The CMS collaboration has searched for new physics in a rare decay of a known particle, using an approach that can be likened to shaking a box containing a birthday present to find a clue about what’s inside
