First Result from the New Muon g-2 Experiment at Fermilab


Nearly twenty years ago a team from Brookhaven National Lab measured the anomalous part aμ of the muon's dipole moment, finding a ~3σ discrepancy against the contemporary Standard Model predictions. The mystery lingered for a time as there were no further measurements, but within a few years a dedicated small team set into
motion a plan to revive the technique at Fermilab. This team grew into the new Muon
g-2 Collaboration, whose result was published earlier this month. In repeating the
experiment, we confirmed the original measurement while utilizing major system upgrades and increased statistics to push the precision below one half ppm. The original incongruity persists and could potentially reach discovery-level significance within the planned run time of the experiment. I will provide a perspective on the
result and our outlook for reaching a few times better resolution with further data.
