Physics Beyond the Standard Model: Recent Results and Current Status of the Muon g − 2 Experiment at Fermilab

In the search for physics beyond the Standard Model, the Muon g − 2 Experiment at Fermilab (E989) has made the most precise measurement of the anomalous magneitc moment of the muon, a_μ, at 0.20 ppm. The value a_μ is extracted from the measurement of the precession frequency of spin-polarized muons stored in a highly uniform, precisely mapped magnetic field. This talk will present the measurement technique and systematic errors associated with the second and third years of E989 data collection as well as the continued improvements in the extraction of a_μ. Additionally, the current tension between the experimental and theoretical values for a_μ will briefly be discussed.
