Muon g-2

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.

Final results from the Fermilab Muon g-2 experiment was announced on June 3, showing a tiny particle continues to act strangely — but that’s still good news for the laws of physics as we know them.

The deviant behavior of a tiny particle called the muon might point to undiscovered forms of matter and energy in the universe. Or it might not.

The third and final result, based on the last three years of data, is in perfect agreement with the experiment’s previous results, further solidifying the experimental world average. This long-awaited value will be the world’s most precise measurement of the muon magnetic anomaly for many years to come.

A Fermilab-led computing project received the second-largest award and was the largest particle physics project granted supercomputer time from the DOE Office of Science INCITE program. The project will continue to further explore numerical simulations to address questions in particle physics.
