A more precise result can expose a new problem or resolve an apparent discrepancy. That is the case with the Muon g-2 experiment with the most precise measurement of the muon and with the mass of the W boson.

The experiment, designed to measure the magnetic moment of the muon, is also sensitive to a particle property called the electric dipole moment.

For 25 years, physicists have been puzzled by the way muons wobble in a magnetic field. Recent collider experiments showing discrepancies to other experiments could be a hint of unknown particles.

On April 18, the winners of some of the most lucrative prizes in science, were announced at the Breakthrough Prize ceremony. The Muon g-2 collaboration won the award in Fundamental Physics for the most precise measurement of the muon to date.

The Muon g-2 experiment at Fermilab received the prestigious Breakthrough Prize in fundamental physics for its precision measurement of the muon.

Argonne researchers commissioned a device that filters out background signals in the Mu2e experiment at Fermilab, which seeks to observe a rare particle physics process. Such an observation would fundamentally change our understanding of the universe.

Fermilab moved the final subdetector for the Mu2e into the experiment hall, marking a major step forward for the collaboration. Once completed, Mu2e will search for a rare muon conversion that may unlock evidence of physics beyond the Standard Model.
