At Fermilab near Chicago, physicists raced muons around the same magnetic ring first used at Brookhaven in the late 1990s and, with more than double the 2023 data, confirmed the tiny particles still wobble in a way the Standard Model could not fully explain
Fermilab's Muon g-2 experiment, using a 50-foot superconducting ring shipped from Brookhaven in 2013, produced the most precise measurement of the muon's magnetic wobble ever taken — and a decade-long lattice calculation now suggests the Standard Model can explain it after all.
