First Results from the Muon g-2 Experiment at Fermilab
Tammy Walton, Fermilab
Evidently, magnetic moments are successful probes for uncovering new physics. The precision measurement of the anomalous magnetic moment of the muon, aμ = (gμ - 2)/2 , continues to play an important role in particle physics. Analyzing approximately 6% of the total data to be collected, the Fermilab Muon g-2 Experiment has measured the anomaly for the positive muon to 460 parts per billion. The measurement agrees with the Brookhaven National Laboratory experimental value and is greater than the recommended Standard Model prediction. The combined measurements increase the tension between experiment and theory from 3.7 to 4.2 standard deviations. This talk presents an overview of the Fermilab Muon g-2 Experiment, the precision measurement of each observable that formed the experimental calculation, the near- future prospects due to having much more unreported data, and the unexpected excitement from the physics community and the world.
