On June 3, scientists working on the Muon g-2 experiment (pronounced “mew-on gee-minus-two”) released the third and final measurement of the muon magnetic anomaly. This result agrees with the published results from 2021 and 2023 but with a much better precision of 127 parts per billion, surpassing the original experimental design goal of 140 parts per billion.
A particle physics experiment decades in the making 鈥� the Muon g-2 experiment 鈥� looks increasingly like it might set up a showdown over whether there are fundamental particles or forces in the universe that are unaccounted for in the current Standard Model. On Aug. 10, the international team of scientists behind Muon g-2 鈥� pronounced 鈥済 minus 2鈥� 鈥� released the world鈥檚 most precise measurement yet of the anomalous magnetic moment of the muon. Calculating the muon鈥檚 magnetic moment at a high precision will indicate whether it is interacting solely with the particles and forces known today, or if unknown particles or forces are out there.
The first results from the Muon g-2 experiment hosted at Fermi National Accelerator Laboratory show fundamental particles called muons behaving in a way not predicted by the Standard Model of particle physics. These results confirm an earlier experiment of the same name performed at Brookhaven National Laboratory. Combined, the two results show strong evidence that our best theoretical model of the subatomic world is incomplete. One potential explanation would be the existence of undiscovered particles or forces.
The Fermi National Accelerator Laboratory 鈥� or Fermilab 鈥� announced that a 680-ton superconducting magnet is secure in its new home and nearly ready for a new era of discovery in particle physics. This achievement follows the delicate, 3,200-mile transport of the magnet’s 17-ton, 50-foot-wide housing ring to the U.S. Department of Energy facility outside Chicago two years ago. The fully assembled magnet will drive high-energy particle experiments as part of an international partnership among 34 institutions, of which the 91探花 is a leading contributor.
