Subatomic Spinning Tops: The Muon g-2 Experiment finds strong evidence for new physics!

Dr. Breese Quinn, Professor in the Department of Physics and Astronomy and Director at the Center for Multimessenter Astrophysics at the University of Mississippi

Almost 20 years ago, an experiment at Brookhaven National Laboratory measured how much muons wobble as they spin in a magnetic field. Their result disagreed with our best theory predictions and represents one of the strongest hints of new physics that we have had in decades. However, the BNL measurement was not precise enough to claim definitively that the evidence amounted to a new discovery. To investigate this longstanding tension, the Muon g-2 experiment was built at Fermilab outside of Chicago, IL to achieve the goal of measuring the muon wobble to an incredible precision of ~100 parts per billion. I will present results from the ongoing Fermilab Muon g-2 experiment, based on the first 6% of our total dataset. These first results confirm the earlier BNL measurement, and give us the strongest evidence to date of brand new physics beyond the Standard Model of particle physics.
