Muon g-2 experiment measures the positive muon anomalous magnetic moment to 0.20 ppm

The Muon g-2 Collaboration is a large group of researchers at different institutes worldwide collaborating on the Muon g-2 experiment. This is a research effort aimed at exploring the interactions of muons, short-lived particles that are essentially heavy electrons, using powerful accelerators at the Fermi National Accelerator Laboratory (Fermilab).
