Precision study of positronium: Testing bound state QED theory

- S. Karshenboim
- Physics
- 8 October 2003

As an unstable light pure leptonic system, positronium is a very specific probe atom to test bound state QED. In contrast to ordinary QED for free leptons, the bound state QED theory is not so well… Expand

Relativistic recoil corrections to the electron-vacuum-polarization contribution in light muonic atoms

- Physics
- 12 December 2011

The relativistic recoil contributions to the Uehling corrections are revisited. We consider a controversy in recent calculations based on different approaches including Breit-type and Grotch-type… Expand

New determination of the electron's mass.

- T. Beier, H. Häffner,
+6 authors G. Werth - PhysicsPhysical review letters
- 19 December 2001

A new independent value for the electron's mass in units of the atomic mass unit is presented, m(e) = 0.000 548 579 909 2(4) u. The value is obtained from our recent measurement of the g factor of… Expand

Precision physics of simple atoms and constraints on a light boson with ultraweak coupling.

- 26 May 2010

Constraint on spin-dependent and spin-independent Yukawa potential at atomic scale is developed. That covers constraints on a coupling constant of an additional photon γ* and a pseudovector boson.… Expand

Virtual light-by-light scattering and the g factor of a bound electron (7 pages)

- R.N.Lee, A. Milstein, I. Terekhov, S. Karshenboim
- Physics
- 2 December 2004

The contribution of the light-by-light diagram to the $g$ factor of an electron and muon bound in a Coulomb field is obtained. For an electron in a ground state, our results are in good agreement… Expand

α2(Zα)4m contributions to the Lamb shift and the fine structure in light muonic atoms

- E. Korzinin, V. Ivanov, S. Karshenboim
- Physics
- 22 November 2013

Corrections to energy levels in light muonic atoms are investigated in order $\alpha^2(Z\alpha)^4m$. We pay attention to corrections which are specific for muonic atoms and include the electron… Expand
