The Muon g-2 experiment searches for telltale signs of new particles and forces by examining the muon’s interaction with a surrounding magnetic field. By precisely determining the magnetic moment of the muon and comparing with similarly exact theoretical predictions, the experiment is sensitive to new physics lurking in the subatomic quantum fluctuations surrounding the muon. A previous experiment performed two decades ago at Brookhaven National Laboratory revealed an intriguing hint of such physics. The highly anticipated result from Fermilab pushes the precision of the experiment into uncharted territory in the quest to confirm or refute that finding.   This result will be presented along with description of the experimental methods and theoretical implications.
