First results from Fermilab muon g-2:  Measurement of the anomalous magnetic moment of the muon

Chris Stoughton

The Fermilab muon g-2 experiment recently released its first measurement of the positive muon magnetic moment anomaly to an accuracy of 0.46 ppm. The anomaly is of interest since it can be predicted with impressive precision and its value is sensitive, via quantum corrections, to the interactions of the muon with the other particles of the Standard Model. Comparison of measurement results and theoretical predictions tests the completeness of the Standard Model, and a significant discrepancy would indicate the need for new physics. I will summarize the wide range of experimental techniques used to make this measurement.  A comparison with the results of the g-2 theory initiative indicates modest tension. I will summarize future prospects from this experiment, other measurements, theoretical progress, and the current state of speculation in the field.
