Muon g-2

A super-precise experiment at Fermilab is carefully analyzing every detail of the muon’s magnetic moment. The Fermilab Muon g-2 collaboration has announced it will present its first result at 10 a.m. CDT on April 7.

From Science, Jan. 27, 2021: Physicists await the Muon g-2 experiment’s results, which could come as early as this spring, to see whether they confirm that muons are slightly more magnetic than theory predicts. If so, it will signal new physics. Fermilab scientists discuss the experiment, as well as the secrecy required to blind themselves from affecting the results.

From Scientific American, Dec. 16, 2020: Researchers have made the most precise measurement of one of the fundamental constants, called the fine-structure constant. Now all eyes are on Fermilab, where the first results of the Muon g-2 experiment are expected to provide the most precise experimental measurement of the muon’s magnetic moment. Alex Keshavarzi, scientist on the Muon g-2 experiment, weighs in on the significance of the measurement.

From Bulgarisches Wirtschaftsblatt, Nov. 11, 2020: Während die Wissenschaftler im Fermi National Accelerator Laboratory des US-Energieministeriums auf die mit Spannung erwarteten ersten Ergebnisse des Muon g-2-Experiments warten, setzen die mitarbeitenden Wissenschaftler des Argonne National Laboratory des DOE weiterhin das einzigartige System ein, das das Magnetfeld im Experiment mit beispielloser Präzision abbildet.
