Abstract
The Muon g − 2 experiment at Fermilab aims to measure the muon magnetic moment anomaly, aμ = (g − 2)/2, with a final accuracy of 0.14 parts per million (ppm). The experiment’s first result was published in 2021, based on data collected in 2018, and in 2023 a new result was published based on twomore years of data taking, 2019 and 2020. The combination of the two results fromFermilab and the previous one from Brookhaven National Laboratory brought the uncertainty on the experimental measurement of aμ to the unprecedented value of 0.19 ppm. This paper will present details about the improvements of statistical and systematic uncertainties on aμ since the 2021 result.

Report
The Muon g−2 experiment at Fermilab measures the muon's magnetic anomaly
with unprecedented precision. Combining results from 2021 and 2023, along with data from Brookhaven, the experiment reached an accuracy of 0.19 ppm. Future analyses of additional datasets aim to achieve a precision of 0.14 ppm, significantly enhancing the comparison between experimental and theoretical values.
