From Le Monde, August 16, 2023: The characteristics muons were analyzed in an ongoing experiment by the Muon g-2 collaboration at Fermilab and the results are shaking up the theory community.
From Universe Today, August 14, 2023: In a recent announcement, scientists at Fermilab and the international Muon g-2 collaboration made the world’s most precise measurement of the muon’s anomalous magnetic moment, improving the precision of their previous measurements by a factor of 2. With this measurement, the collaboration has achieved its goal of decreasing systematic uncertainties caused by experimental imperfections.
From Univision, August 11. 2023 (Right click to translate to English): The Muon g-2 results announced last week confirm muons did not behave as predicted by the current theory of physics, the Standard Model. The announcement brings physicists closer to discoveries such as whether there are more types of matter and energy that make up the universe than have been accounted for.
From The Conversation, Aug. 10, 2023: The new results of the Muon g-2 experiment are summarized by a group of Postdocs from the University of Liverpool. The latest results examined four times as many muons as the 2021 result, cutting the total uncertainty by a factor of two. This makes the measurement the most precise determination of the muon’s wobble ever made on Muon g-2.
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 showdown between theory and experiment that may uncover new particles or forces.
A large number of scientists are working on improving the Standard Model prediction of the value of muon g-2 using new data and new lattice calculations. By measuring and calculating this number to ultra-high precision, scientists can test whether the Standard Model is complete.
From the Innovation News Network, May 31, 2023: Editor Georgie Purcell interviews Sean Foster, Research Scientist at Boston University, and Elia Bottalico, Postdoctoral Researcher at the University of Liverpool, who are both heavily involved on the Muon g-2 experiment. The g-2 collaboration scientists are in the final stages of data analysis for Runs 2 and 3 and are preparing to announce the results later this year.
From the Universities Research Association, October 31, 2022: Brynn MacCoy is a physics doctoral candidate at the University of Washington and the Fall 2019 URA Visiting Scholar Program (VSP) Awardee. With an extension of URA assistance, MacCoy returned to Fermilab earlier this year allowing her to install the Minimally Intrusive Scintillating Fiber Detector.
From Scientific American, October 2022: For several decades after the invention of the Standard Model, several physics measurements suggest that novel particles and forces exist in the universe. This article was originally published and titled, “When Particles Break the Rules” and includes the combined results from the Fermilab g-2 experiment and the previous trial at Brookhaven that add up to a probability of less than 0.01 percent that this anomaly is a statistical fluke.
From Brookhaven National Laboratory, October 11, 2022: Brookhaven National Lab announced yesterday that two of their scientists who led the “E821 g-2” experiment at BNL from 1990 through 2004 received the APS’s 2023 W.K.H. Panofsky Prize in Experimental Particle Physics. William M. Morse and Bradley Lee Roberts received the honor for their leadership and technical ingenuity in achieving a measurement of the muon anomalous magnetic moment with a precision suitable to probe Standard Model.
