Precision tests of QED

AIP Conference Proceedings, 1984
The major precision tests of QED are reviewed. At the present time, there are no serious conflicts between theory and experiment. However, there are various possibilities for refining the tests and some of them depend on better information from high energy physics experiments.

QED Effects in Helium and Comparisons with High Precision Experiment

Physica Scripta, 2001
A large body of work to calculate nonrelativistic energies, relativistic corrections, and quantum electrodynamic (QED) energy shifts in helium is reviewed and compared with experiment. Of particular significance are measurements of the QED (Lamb) shift for the low-lying S-states of helium, where the accuracy rivals the best measurements in the ...

Accurate tests of QED with precision spectroscopy of molecular deuterium [PDF]

, 2022
Molecular hydrogen, in the view of its simplicity, is well suited for testing quantum electrodynamics (QED) for moleculesas well as for searching for new physics beyond the standard model such as new forces or extra dimensions. Furthermore,molecular hydrogen possesses a wide structure of ultranarrow rovibrational transitions with different ...

Precision spectroscopy of positronium: Testing bound-state QED theory and the search for physics beyond the Standard Model [PDF]

Physics Reports, 2022
Positronium (Ps) is an exotic hydrogenic atom composed of an electron bound to a positron via the Coulomb force. Being composed of two low-mass leptons, positronium is, for all practical purposes, fully described by quantum electrodynamics (QED).

High-precision ϵ-expansions of three-loop master integrals contributing to the electron g–2 in QED [PDF]

Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2001
In this Letter we calculate at high-precision the Laurent expansions in ϵ=(4−D)/2 of the 17 master integrals which appeared in the analytical calculation of 3-loop QED contribution to the electron g–2, using difference and differential equations.
