Latest Result of the Fermilab Muon 𝒈−2 Experiment

The Fermilab Muon $g-2$ Experiment aims to make precise measurements of the anomalous magnetic moment of the muon (aμ). The previous result was published in 2021 and the experimental result was 3.3 σ larger than the Standard Model (SM) prediction and was in good agreement with the measurement of the Brookhaven Muon $g-2$ experiment. In the summer of 2023, we released the latest result of aμ which is measured to 0.21 ppm, with a factor of 2 improvement in the precision from the Run-2 and Run-3 datasets. Combining with the Run-1 and Brookhaven results, the new world average aμ is measured to 0.19 ppm. In this proceeding, we will present a brief overview of the experiment, the improvements in the Run-2 and Run-3 analysis, and the outlook of the experiment.
