quantum electrodynamics of bound systems

Oral presentation

77. Tests of physics beyond the standard model with the g factor of few-electron ions

tests and extensions of the Standard Model of elementary particles

Oral presentation

emphasized textIn this contribution, we discuss the theory of the bound-electron g factor. This quantity can be measured nowadays to high precision in Penning-trap setups. The collaboration of theory and experiment enables impactful and detailed tests of quantum electrodynamics in a strong background electric field, and a competitive determination of fundamental constants [1] and nuclear...

103. Three-Loop Corrections to Lamb Shift in Muonium and Positronium

Prof. Michael Eides (University of Kentucky)

quantum electrodynamics of bound systems

Oral presentation

Hard spin-independent three-loop radiative corrections to energy levels in muonium and positronium are calculated.
These corrections could be relevant for the new generation of precise 1S-2S and 2S-2P measurements in muonium and
positronium.

23. Towards a bound-state relativistic QED approach

David Ferenc (ELTE, Eötvös Loránd University, Institute of Chemistry, Budapest, Hungary)
