D16: Precision Tests of Fundamental Physics and Dark Matter Searches

Wed. April 3, 3:45 p.m. – 3:57 p.m. PDT

Ballroom B5, Floor 2

The new Muon g–2 experiment at Fermilab, while primarily designed to measure the anomalous magnetic moment of the muon, can also be used to make a world-leading measurement of the muon's electric dipole moment (EDM). The Standard Model predicts that this should be orders of magnitude smaller than what is currently measurable with current experiments. However, some BSM models predict different mass scaling, or decouple the EDM from the lepton masses altogether, allowing for much larger EDMs. Any observation of a muon EDM at Fermilab would therefore be a discovery of new physics, as well as a new source of CP violation in the lepton sector. Even if no EDM is observed, making more precise measurements allows more stringent limits to be set, making the muon EDM an excellent tool for new physics searches. This talk will cover the strategies used at Fermilab to search for a muon EDM, with a focus on using straw tracker data, and will give an update on the current status of the analysis.
