Muon g-2

Science magazine highlights their top picks of significant science stories in 2025. Fermilab’s Muon g-2 announcement his year is included in this prestigious listing.

Gray Putnam, James Mott, Lauren Yates and Chris Jensen are this year’s recipients of the URA Honorary Awards. The awards are presented each year to recognize significant contributions to research at Fermilab.

Throughout this year, Fermilab’s dedicated scientists, engineers, technicians and operations staff came together to drive discoveries, advance American innovation and prepare the lab for a bright future.

Fermilab’s Muon g-2 collaboration has given its final word on the magnetic moment of the muon. Though the experimental measurement will likely now remain stable for several years, theorists expect to make rapid progress to reduce uncertainties and resolve tensions underlying the SM value.

Fermilab released the third and final measurement of the muon magnetic anomaly. The Muon g-2 collaboration describes the result in the recently published paper in the Physical Review Letters.

Fermilab’s Muon g-2 collaboration announced the final result on the magnetic moment of the muon. The new measurement agrees closely with a significantly revised Standard Model prediction.

There are an array of experiments, like the Muon g-2 experiment at Fermilab, that are looking to see if an elusive fifth force might be at work.

Experiments that uncover the possibility of new forces, like the Muon g-2 experiment at Fermilab, might help researchers examine the trajectories of well-documented asteroids in hopes of detecting anomalies that could provide evidence of such a fifth force.

When theory and experiment disagree, it could mean new physics. With the recent announcement of the most precise measurement of the magnetic moment of the muon, the anomaly is no more.

Muon g-2 collaborator describes the latest precision of the muon measurement to an an 11,000-pound elephant standing on a bathroom scale. The scale is so precise, it can measure if a couple of sunflower seeds are placed on the elephant’s back.
