What is Muon g-2? The Muon g-2 experiment measures what happens as muons circulate through a 50-foot-diameter electromagnet storage ring. The muons, which have intrinsic magnetism and spin (sort of like spinning toy tops), start off with their spins aligned with their direction of motion.
7 Απρ 2021 · The long-awaited first results from the Muon g-2 experiment at the U.S. Department of Energy’s Fermi National Accelerator Laboratory show fundamental particles called muons behaving in a way that is not predicted by scientists’ best theory, the Standard Model of particle physics.
14 Αυγ 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.
With the development of Quantum Field Theory, the reasons for the anomaly were understood and increasingly precise calculations and measurements have lead to a triumph of particle physics: The agreement between the measured value of the anomalous magnetic moment of the electron and the theoretical prediction (which involves the full panoply of ...
15 Μαρ 2017 · How does it work? The Mu2e detector is a particle physics detector embedded in a series of superconducting magnets. The magnets are designed to create a low-energy muon beam that can be stopped in a thin aluminum stopping target.
1 Φεβ 2022 · Precise calculations and measurements of this fundamental quantity provide a stringent test of the SM and a window to the physics beyond. In light of the first result published by the Fermilab Muon g − 2 experiment, this article reviews the current status of the experimental measurement and theoretical prediction of the muon anomalous ...
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]
