The ALICE collaboration shows that different bound states of a charm quark and its antimatter counterpart are differently modified by quark–gluon plasma, opening new avenues for studying this special state of matter and its effects

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

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

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

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 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

The ATLAS and CMS collaborations have searched for matter–antimatter asymmetry in the interaction between the Higgs boson and the tau lepton

The CMS experiment awaits LHC Run 3 to explore several analyses showing small disagreements with theory expectations

The resultant particles quickly spread around the globe, potentially influencing Earth’s climate on an intercontinental scale
