The Muon g-2 experiment at Fermilab received the prestigious Breakthrough Prize in fundamental physics for its precision measurement of the muon.

Argonne researchers commissioned a device that filters out background signals in the Mu2e experiment at Fermilab, which seeks to observe a rare particle physics process. Such an observation would fundamentally change our understanding of the universe.

Fermilab moved the final subdetector for the Mu2e into the experiment hall, marking a major step forward for the collaboration. Once completed, Mu2e will search for a rare muon conversion that may unlock evidence of physics beyond the Standard Model.

Science magazine highlights their top picks of significant science stories in 2025. Fermilab’s Muon g-2 announcement his year is included in this prestigious listing.

Fermilab released the third and final measurement of the muon magnetic anomaly. The Muon g-2 collaboration describes the result in the recently published paper in the Physical Review Letters.

The deviant behavior of a tiny particle called the muon might point to undiscovered forms of matter and energy in the universe. Or it might not.

The MUonE experiment at CERN could search for dark matter particles in addition to studying the muon’s magnetic moment.

In recent years, a new SM prediction of the muon g-2 has emerged that questions whether the discrepancy exists at all, suggesting that there is no new physics in the muon. Alex Keshavarzi, a member of the Muon g-2 Experiment and the Muon g-2 Theory Initiative, discusses what is next for the final result for g-2 in 2025.
