The MACE experiment searches for muonium (a muon bound to an electron) spontaneously converting to antimuonium — a process forbidden by the Standard Model that would reveal new physics at 10-100 TeV scales. Based on the conceptual design published in Nuclear Science and Techniques (2026), aiming for 100x better sensitivity than the 1999 PSI experiment. The signature: a fast electron (MeV) and a slow positron (13.5 eV) — six orders of magnitude apart.","shortDescription":"A forbidden flip"}}
