From Business AM (Belgium), January 1, 2022: In 2021, physicists around the world conducted some interesting experiments examining the Standard Model and ways it can’t explain every mystery of the universe. Last April, members of the Muon g-2 experiment at Fermilab announced their first measurement of the muon’s magnetic moment. This experiment was important was because the measurement did not perfectly match the Standard Model’s prediction of the magnetic moment.

Researchers from more than 50 countries collaborate with Fermilab to develop state-of-the-art technologies and solve the mysteries of matter, energy, space and time. Take a look at 10 ways Fermilab and its partners advanced science and technology in 2021.
Building experimental evidence suggests that the electron, muon and tau may feel different forces.
From Fuentitech, October 19, 2021: Physicists have long wondered if muons, electrons, and other leptons make a difference other than mass. The latest LHCb results suggest that the answer may be “yes” by revealing two minor anomalies that continue the strange pattern of “lost” muons shown in recent data from the LHCb. In April, the Muon g-2 experiment at Fermilab also found a discrepancy from the Standard Model but future results may also shed light on these differences.
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 Portable TV, I Don’t Understand, July 18, 2021: William Shatner interviews Saskia Charity of Fermilab on what is a muon and the meaning of the Muon g-2 experiment result.
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 University of Chicago News, June 18, 2021: Fermilab’s muon g-2 result announced in April has theorists scratching their heads about muons behaving slightly differently than predicted in their giant accelerator.
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.
From the Dallas Morning News, June 13, 2021: The results of the April 7 Muon g-2 result strongly disagreed with the standard model and it is incumbent upon us now to explain this observation, writes Stephen Sekula, chair of physics and an associate professor of experimental particle physics at Southern Methodist University.
