The Muonic Helium Lamb Shift experiment — •Marc Diepold and The CREMA Collaboration — Max-Planck-Institute of Quantum Optics, Garching

This poster gives a detailed overview about the working principle and setup of the Muonic Helium Lamb shift experiment at the Paul-Scherrer-Institute in Switzerland.

Newly implemented features in the ongoing data analysis are emphasised and preliminary results for different 2S→2P transitions measured in both the µ4He+ and µ3He+ exotic ions are provided.

These results shed new light on the Proton Radius Puzzle created by the 7 sigma discrepancy between different determinations of the rms charge radius of the proton.
