Standard Model

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

A bus-sized neutrino detector housed at the Fermilab has investigated the anomalies of previous experiments involving sterile neutrinos.

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.

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.

The 1980s and 1990s were a unique time for particle physics in the aftermath of the Standard Model in which Fermilab provided many contributions. The upcoming International Symposium on the History of Particle Physics at CERN will include research from Fermilab’s Tevatron.

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.

On July 21, 2000, the DONUT collaboration at Fermilab announced the first direct evidence for tau neutrinos. The particles remain elusive to this day, but physicists continue to seek new ways of studying them.

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.
