41. Precision Tests of Quantum Electrodynamics with Highly Charged Ions

Precise measurements of magnetic moments and masses with individual particles in Penning traps have opened opportunities for fundamental tests of physical theories. The determination of the magnetic moment of the electron bound in highly charged ions is a sensitive test of the theory of bound-state Quantum Electrodynamics. At the same time, such precision experiments - together with atomic...

High precision spectroscopy has been always the driving force for new fundamental theories in physics. The so called proton size problem is a so far unexplained disagreement of the value of the proton charge radius extracted from the muonic spectroscopy, hydrogen spectroscopy and elastic electron-proton scattering by more than 5 sigma \cite{Antognini2013}. Our experiment is highly suitable...
