Looking for Answers with Muons at g-2 and Mu2e

HEP Special Seminar

Abstract: Now is an exciting time to do particle physics! Recent discoveries require additional exploration. In addition, there are many open questions: What is dark matter? Where is antimatter? Why are there three families of quarks and leptons?

The Muon Campus at Fermilab, which hosts the g-2 and Mu2e experiments, is designed to look for answers to some of these pressing questions by using high-intensity muon beams. The g-2 experiment will measure the anomalous magnetic moment of the muon to a precision of 0.14 parts per million. This can firmly establish the deviation from the Standard Model prediction, observed at Brookhaven National Laboratory, with more than 5 sigma confidence level. Mu2e will search for a neutrinoless muon-to-electron conversion process with almost four orders of magnitude of sensitivity improvement relative to the current best limit. As with g-2, the observation of this process will be an unambiguous sign of physics beyond the Standard Model.

The searches at g-2 and Mu2e are complementary to the high-energy program at the Large Hadron Collider and are sensitive to a wide range of new physics models. With their improved sensitivities over past experiments, these searches provide an excellent opportunity to make the next big discovery.
