From NPR, August 20, 2023
NPR’s Ayesha Rascoe speaks to Esra Barlas Yücel, a researcher at University of Illinois at Urbana-Champaign, about Fermilab’s most precise measurements of the muon particle’s magnetic wobble.

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 Big Think, Jan. 10, 2023: While the Standard Model is the best theory available in modern physics to explain subatomic physics, it cannot explain why antimatter isn’t observed in nature or provide an explanation for dark matter and dark energy. Don Lincoln explains how recent measurements of muons and electrons are propelling the idea that there may be undiscovered laws of nature yet to discover.
From the Finding Genius Podcast, May 4, 2022: The Muon g-2 project led by Fermilab holds the potential to reveal some of the universe’s inner workings. Chris Polly joins the Finding Genius Podcast to explain his work on the Muon g-2 project, how the experiment studies muons and what the results mean relative to the Standard Model of particle physics.
From Discover Magazine, December 19, 2021: In April, an international collaboration of more than 200 scientists, led by Fermilab reported findings that may open a door to physics that transcends the Standard Model. Muon g-2’s magnetic moment goes beyond the Standard Model.
From Institute of Physics, November 29, 2021: Professor Mark Lancaster received the James Chadwick Medal from the Institute of Physics for his distinguished work of precise measurements in particle physics, particularly of the W boson mass and the muon’s anomalous magnetic moment in April 2021.
From The Naked Scientists, October 12, 2021: Scientists at Fermilab may have uncovered something in muons beyond our understanding-an interview with Fermilab’s Brendan Casey on Muon g-2 and the magnetic strength of muons, their strange behavior, and how they could change our understanding of the universe.
From How Stuff Works, July 1, 2021: Fermilab’s Muon g-2 result announcement in April 2021 introduced the world to the muon. Although the particle was first discovered in the late 1930’s, the muon made international headlines confirming previous findings that the muon behaves in a way that contradicts the Standard Model of Particle Physics.
From Discover, June 23, 2021: Muons drew the attention of physicists around the world after an experiment at Fermilab demonstrated that they’re far more magnetic than expected.
From CERN, June 15, 2021: A new study shows a class of new unknown particles that could account for the muon’s magnetism, known as leptoquarks, also affects the Higgs boson’s transformation into muons.
