The LHCb collaboration has observed time-dependent matter–antimatter asymmetry in the decays of strange beauty particles into charged kaons

The ATLAS and CMS collaborations used the full LHC Run 2 dataset to obtain new insights into the interaction

The measurements are consistent with predictions for “normal” matter and pave the way for future precision studies

The BASE collaboration reports the first laboratory search for an interaction between antimatter and a candidate particle for dark matter

The AEgIS collaboration at CERN has found a new way of making long-lived positronium atoms for antimatter gravity experiments

The ALPHA-g and GBAR experiments have received their first beams of antiprotons

The ATLAS collaboration presents its latest search for heavy Majorana neutrinos

The ALPHA collaboration has observed a new electronic transition in the antihydrogen atom
