PhD project: The Mu3e experiment

Supervisor: Prof. Gavin Hesketh

The Standard Model is remarkably successful, and yet leaves many open questions, such as the nature of dark matter, the mechanism which generated the matter-antimatter asymmetry in the universe, and why are there three generations of fermions. New experimental data is needed to point us towards a deeper theory of the universe, but so far the Large Hadron Collider (LHC) has not turned up such a discovery. However, there are hints in recent precision measurements of the muon, including the first data from Muon g-2 published in 2021. This PhD project is on the Mu3e experiment, which will expand the study of precision muon physics, providing complimentary information on the tension observed at Muon g-2 and probing for new physics at mass scales far beyond the direct reach of the LHC.
Using an innovative HV-CMOS silicon tracker design, Mu3e will search for the forbidden decay of a muon to three electrons, extending the sensitivity to this process by 4 orders of magnitude over current limits. This will place strict limits on new physics - or turn up a groundbreaking discovery. The experiment is currently under construction at the Paul Scherrer Institut (Switzerland) and will start data-taking in 2024, with physics data in 2025. This PhD project offers the opportunity to be involved in the commissioning, operation, and data analysis on Mu3e, giving experience in a broad range of experimental particle physics skills. The project supervisor, Prof. Gavin Hesketh, is the Physics Coordinator for Mu3e, and UCL will play a central role in producing first results from the experiment.
