Muon g-2 Experiment

Physicists are exploring the development of a muon collider — an advanced particle accelerator that could reveal new insights into the nature of our universe. Though great challenges exist in studying fast-decaying muons, technological advancements in accelerators, magnets and detectors could make building the collider a reality. Recent workshops hosted by Fermilab brought together researchers from around the globe to address some of these challenges.

In 2024, Fermilab made significant scientific progress, including advancing preparations for the Deep Underground Neutrino Experiment and conducting groundbreaking quantum research. The laboratory also continued its strong international collaborations — including involvement with the CMS experiment at CERN — and made strides in developing emerging technologies with wide applications beyond physics.

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.
