Precision measurements of electromagnetic couplings are fundamental tests of quantum electrodynamics (QED) and powerful probes of new physics beyond the Standard Model (BSM). The electron anomalous magnetic moment ae = 1 2 (ge 2) is among the most precisely measured observables in nature [1, 2]. The muon counterpart aμ is measured to 1 part in 107 [3] and reports a longstanding 3 4 deviation from the SM prediction, which may be a harbinger of new physics.
