US EditionFermilab: Muon G-2 Announces Most Precise Measurement of the Magnetic Anomaly of the Muon
- The Muon g-2 experiment at Fermilab announced on June 3, 2025, the most precise measurement of the muon's anomalous magnetic moment in Batavia, Illinois.
- This finding builds on many years of prior studies conducted at a New York research facility and extensive theoretical work aimed at addressing inconsistencies with the Standard Model.
- The experiment measured the muon spin precession with an uncertainty of 127 parts per billion, surpassing original goals and confirming earlier results from 2021 and 2023.
- The updated theoretical prediction from the Muon g-2 Theory Initiative, supported by new computational methods, now aligns more closely with the experiment, reducing previous tensions.
- The findings reaffirm the Standard Model’s accuracy but leave open the pursuit of new physics, with follow-up experiments planned and ongoing international collaboration continuing.
