Department Colloquium | The First Measurement of the Muon Anomalous Magnetic Moment from the Fermilab Muon g-2 Collaboration

This colloquium will cover the physics and methods behind Fermilab's Muon g-2 experiment, along with the long-awaited results from Run-1. The experiment was undertaken to resolve the tension between the Standard Model and the previous measurement taken at Brookhaven National Labs. The measured value of the muon anomalous magnetic moment is $a_\mu(FNAL) = 116592040(54)×10^{−11}$. This result is in good agreement with Brookhaven's previous measurement. The new world average, $a_\mu(Exp) = 116592061(41)×10^{−11}$, shows a difference from the theoretical value, $a_\mu(Exp) = 116591810(43)×10^{−11}$, of 4.2 standard deviations, strongly hinting at physics beyond the Standard Model. The experiment requires the simultaneous measurement of the muon precession frequency, the magnetic field, and the muons' distribution in the field. All three of these measurements will be discussed in context, along with the main systematic corrections and uncertainties.
