The Muon g-2 Experiment at Fermilab

The muon magnetic anomaly, $a_μ$, is a powerful test of the Standard Model of particle physics. A new experiment at Fermilab has recently measured $a_μ$ with unprecedented precision, confirming the results of the earlier Brookhaven experiment and strengthening the tension with the prediction of the Standard Model as determined by dispersive methods. We here describe the experimental technique, recapitulate the recent result, and discuss some of the improvements made for subsequent analyses.
