Description
The Fermilab Muon $g-2$ Experiment aims to make precise measurements of the anomalous magnetic moment ($a_{\mu}$) of the muon. The first measurement of the experiment is $3.3\sigma$ larger than the Standard Model (SM) prediction. The measurement is in good agreement with the previous result with improved precision. The uncertainty of the measurement is $0.46~ppm$ which gives the most precise measurement on $a_{\mu}$ up to date. The new world average value is $4.2\sigma$ larger than the SM prediction. This result further strengthens the evidence for new physics beyond the Standard Model (BSM).
The analysis of Run 2+3 is underway. With improvement and optimization after Run1, the systematic uncertainties will be further reduced. In early July, the Run 5 data taking was finished. Up to date, about 19xBNL data in total were collected.
