16. Bound-state QED calculations and the hydrogen molecular ion spectroscopy

Vladimir Korobov (Joint Institute for Nuclear Research (JINR))

In our presentation we would like to discuss calculating of the largest contributions to the ro-vibrational energies at $m\alpha^8$ order for the hydrogen molecular ions H$_2^+$ and HD$^+$ (HMI). We expect to provide new data, which enable to achieve a relative precision of $10^{-11}$ and even better for the fundamental transitions in HMI. Along with experimental results that should have a...

8. Quantum electromagnetic nonlinearity affecting charges and dipole moments

Owing to the virtual electron-positron pair creation, quantum electrodynamics (QED) may be effectively treated as a nonlinear classical theory of electromagnetic fields. The corresponding mutual and self- interaction of electromagnetic fields is important where these are as strong as magnetic fields of magnetars, electric fields of quark stars, and fields in close vicinity of elementary...

28. Recoil correction to the proton finite-size contribution to the Lamb shift in muonic hydrogen

Dr Evgeny Yu. Korzinin (D. I. Mendeleev Institute for Metrology, St. Petersburg 190005, Russia)

The Lamb shift in muonic hydrogen was measured some time ago to a high accuracy. The theoretical prediction of this value is very sensitive to the proton finite-size effects. The proton radius extracted from muonic hydrogen is in contradiction with the results extracted from elastic electron-proton scattering. That creates a certain problem for the interpretation of the results from the...
