From Back Reaction, June 13, 2019: The so-called muon g-2 anomaly is a tension between experimental measurement and theoretical prediction. The most recent experimental data comes from a 2006 experiment at Brookhaven National Lab. A new experiment is now following up on the 2006 result: The Muon g-2 experiment at Fermilab.
Muon g-2 has begun its second run to search for hidden particles and forces. Muon g-2 collaborators have performed upgrades to improve the experiment’s precision and increase the amount of data it generates. As the experiment starts up again, scientists expect to make the world’s most precise measurement of the muon’s anomalous magnetic moment, which could tell us whether additional, undiscovered particles exist in the universe.
From Kyoto University, Feb. 27, 2019: In this five-minute video, University of Washington scientist and Fermilab collaborator Kim Siang Khaw explains Fermilab’s Muon g-2 experiment and how it may reveal unknown particles lurking in our universe.
Physicists often find thrifty, ingenious ways to reuse equipment and resources. What do you do about an 800-ton magnet originally used to discover new particles? Send it off on a months-long journey via truck, train and ship halfway across the world to detect oscillating particles called neutrinos, of course. It’s all part of the vast recycling network of the physics community.
These international projects, selected during the process to plan the future of U.S. particle physics, are all set to come online within the next 10 years.
