Abstract:
The anomalous magnetic moment of the muon, or muon g-2, has generated a tremendous amount of research activity over the past decade. As a quantity that can be predicted given the particle and interaction content of the universe, it is an ideal target for precision measurement. Experimentalists and theorists, intrigued by the persisting larger-than-three standard deviations discrepancy between the Standard Model prediction and the measurement from Brookhaven National Lab, are working on their ends to improve the precisions of the experimental and predicted values of muon g-2.In this colloquium, I will give an overview of the rich history of the muon g-2. I will then briefly mention the two next-generation muon g-2 experiments in the world before switching my focus to the Fermilab Muon g-2 experiment. Preliminary blinded results demonstrating the mature state of the Run 1 analysis will be presented, together with the current status of the experiment in Run 2. Finally, I will discuss the prospects of the experiment.
