The finding will help space- and balloon-based searches for antimatter that may have originated from dark matter

The CAPP axion haloscope at the CAST experiment has hunted for axions from the Milky Way’s “halo” of dark matter, and has narrowed down the theoretical space in which to look for these hypothetical particles

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

CMS measured the top-quark pair production cross section

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
