Delbruck scattering and the g-factor of a bound electron
Savely G. Karshenboim, Alexander I. Milstein
The leading contribution of the light-by-light scattering effects to g-factor of a bound electron is derived. The corresponding amplitude is expressed in terms of low-energy Delbru…
Hadronic effects in leptonic systems: muonium hyperfine structure and anomalous magnetic moment of muon
S. I. Eidelman, S. G. Karshenboim, V. A. Shelyuto
Contributions of hadronic effects to the muonium physics and anomalous magnetic moment of muon are considered. Special attention is paid to higher-order effects and the uncertainty…
g factor in a light two body atomic system: a determination of fundamental constants to test QED
S. G. Karshenboim, V. G. Ivanov
Energy levels of a two-body atomic system in an external homogeneous magnetic field can be presented in terms of magnetic moments of their components, however, those magnetic momen…
Precision Optical Measurements and Fundamental Physical Constants
Savely G. Karshenboim
A brief overview is given on precision determinations of values of the fundamental physical constants and the search for their variation with time by means of precision spectroscop…
Precision study of positronium and precision tests of the bound state QED
Savely G. Karshenboim
Despite its very short lifetime positronium provides us with a number of accurate tests of the bound state QED. In this note a brief overview of QED theory and precision experiment…
