On June 3, 2025, the Muon g-2 Collaboration will release its final determination of the muon magnetic anomaly, aμ. Its determination represents an important test of both the Standard Model's completeness and hypothetical physics landscapes.

 

The anomaly is obtained from the ratio of the measured values of the muon anomalous precession frequency and the proton Lamor precession frequency in the 1.5 Tesla, Brookhaven superconducting storage ring used in the famous BNL E821 muon g-2 experiment. The talk will describe the experimental methods and analysis techniques used in the FNAL g-2 measurement (that stand on the shoulders of the BNL experiment). From the painstaking accumulation of 21x BNL positron statistics, to such innovations as in-vacuum trackers and RF electric quadrupoles, we'll describe the road from BNL's to FNAL's result.

 

We'll then discuss the FNAL final result for aμ, and its comparison with the BNL measurement and the SM prediction.
