MACE is a newly launched particle physics experiment in China that searches for spontaneous transformations of its muonium antimatter twin, antimuonium, featuring ultra-precise beams and detectors. Led by researchers at Sun Yat-sen University and the Institute of Modern Physics of the Chinese Academy of Sciences, the project targets an elusive process that would violate lepton flavor conservation in the Standard Model. By focusing on this clean leptonic system, the experiment offers a direct way to test whether hidden forces or particles alter how fundamental matter behaves.
The MACE setup pushes sensitivity more than 100 times beyond a 1999 benchmark, aiming to detect conversion probabilities as low as 10⁻¹³. This leap relies on a powerful surface muon beam, a custom silica aerogel target for efficient muonium production, and finely tuned detectors that can distinguish genuine signals from overwhelming background noise. In an initial Phase I, MACE also studies rare muonium decay channels and lepton flavor–violating events, broadening its scientific reach.
