Enter Fermilab, the place a brand new campus dedicated to learning muons was being constructed.
“That opened up a world of possibility,” Dr. Polly recalled in his biographical article. By this time, Dr. Polly was working at Fermilab; he and his colleagues may redo the g-2 experiment there, with extra precision. He grew to become the undertaking supervisor for the experiment.
To conduct the experiment, nonetheless, they wanted the 50-foot magnet racetrack from Brookhaven. And so in 2013, the magnet went on a 3,200-mile odyssey, principally by barge, down the Eastern Seaboard, round Florida and up the Mississippi River, then by truck throughout Illinois to Batavia, house of Fermilab.
The magnet resembled a flying saucer, and it drew consideration because it was pushed south throughout Long Island at 10 miles per hour. “I walked along and talked to people about the science we were doing,” Dr. Polly wrote. “Moving it through the Chicago suburbs to Fermilab offered another chance for outreach. It stayed over one night in a Costco parking lot. Well over a thousand people came out to see it and hear about the science.”
The experiment began up in 2018 with a extra intense muon beam and the purpose of compiling 20 occasions as a lot information because the Brookhaven model.
Meanwhile, in 2020, a bunch of 170 specialists generally known as the Muon g-2 Theory Initiative printed a new consensus value of the theoretical value of muon’s magnetic moment, primarily based on three years of workshops and calculations utilizing the Standard Model. That reply bolstered the unique discrepancy reported by Brookhaven.
Reached by cellphone on Monday, Aida X. El-Khadra, a physicist on the University of Illinois and a co-chair of the Muon g-2 Theory Initiative, stated they’d been ready for this outcome for a very long time.
“I have not had the feeling of sitting on hot coals before,” she stated.
On the day of the Fermilab announcement one other group, utilizing a special method generally known as a lattice calculation to compute the muon’s magnetic second, received a special reply than Dr. El-Khadra’s group.
