Funded Activity Summary

Shedding Light on the Proton Radius Puzzle with Ultracold Helium. This project aims to shed light on an outstanding discrepancy in physics known as the proton radius puzzle, first seen in hydrogen but now being studied in helium. Capitalising on existing international collaboration between experiment and theory to exploit the advantages of ultracold helium, this project aims to determine the isotopic nuclear charge radius difference with unprecedented precision, using our state-of-the-art quantum electrodynamic theory. This will not only answer fundamental questions about helium atomic structure, but may also reveal new physics beyond the current Standard Model. The validation of atomic structure theory should provide benefits in applications including the realisation of more accurate atomic clocks.
