Muon g − 2 (pronounced "gee minus two") is a particle physics experiment at Fermilab to measure the anomalous magnetic dipole moment of a muon to a precision of 0.14 ppm, [1] which is a sensitive test of the Standard Model. [2]
5 wrz 2023 · The Muon g-2 experiment at Fermilab aims to measure the muon magnetic moment anomaly, aμ = (g − 2)/2, with a final accuracy of 140 parts per billion. The experiment’s first result from the 2018 dataset, Run 1, was published in 2021 and confirmed the previous result obtained at Brookhaven National Laboratory with a similar sensitivity.
14 sie 2023 · The Muon g-2 experiment at Fermilab has made the world’s most precise measurement yet of the anomalous magnetic moment of the muon. It improves the precision of their previous result by a factor of 2 and sets up a showdown between theory and experiment over 20 years in the making.
Among other things, the theory predicts an anomalously high value for the muon's magnetic moment ‘g’, which is a little more than 2, hence the name of the experiment. Six physicists joined forces in 1959 to try and measure this value on CERN’s first accelerator, the Synchrocyclotron.
11 sie 2023 · The Fermilab experiment reused a storage ring originally built for the predecessor Muon g-2 experiment at DOE’s Brookhaven National Laboratory that concluded in 2001. In 2013, the collaboration transported the storage ring 3,200 miles from Long Island, New York, to Batavia, Illinois.
Scientists working on Fermilab's Muon g-2 experiment released the world's most precise measurement yet of the magnetic moment of the muon, bringing particle physics closer to the ultimate...
Why move 600 ton, 15 meter wide metal ring half-way across U.S.? Why muons? What’s muon g-2? What do we learn from it? Why we are moving it to Fermilab? It all starts from something simple... Where is the fun part (anomaly)? Electrons, do we really ‘see’ g=2 as predicted by Dirac? Where does this 0.1% deviation comes from? Empty space ?!
