چکیده
We calculate radiative corrections to the Lamb shift of order α3(Zα)5m and radiative corrections to hyperfine splitting of order α(Zα)EF generated by the diagrams with insertions of radiative photons and electron polarization loops in the graphs with two external photons. We also obtain the radiativerecoil correction to hyperfine splitting in muonium generated by the diagrams with the τ polarization loop.

Corrections of Order Α(zα) to Hyperfine Splitting and Lamb Shift
Corrections to hyperfine splitting and Lamb shift of order α(Zα) induced by the diagrams with radiative photon insertions in the electron line are calculated in the Fried-Yennie gauge. These contributions are as large as −7.725(3)α(Zα)/(πn)(mr/m) m and −0.6711(7)α(Zα)/(πn)EF for the Lamb shift and hyperfine splitting, respectively. Phenomenological implications of these results are discussed wi...

Corrections of order α(Zα)m to the Lamb shift and corrections of order α3(Zα)EF to hyperfine splitting generated by the insertions of the three-loop one-particle reducible diagrams with radiative photons in the electron line are calculated. The calculations are performed in the Yennie gauge.
متن کاملCorrections to Hyperfine Splitting and Lamb Shift Induced by the Overlapping Two-loop Electron Self-energy Insertion in the Electron Line
Contributions to HFS and to the Lamb shift intervals of order α(Zα) induced by the graph with the two-loop overlapping electron self-energy diagram inserted in the electron line are considered. Explicit expression for the overlapping two-loop self-energy diagram in the Fried-Yennie gauge is obtained. Contributions both to HFS and Lamb shift induced by the diagram containing such subgraph are ca...
متن کاملFirst Corrections to Hyperfine Splitting and Lamb Shift Induced by Diagrams with Two External Photons and Second Order Radiative Insertions in the Electron Line
Contributions to HFS and to the Lamb shift intervals of order α(Zα) induced by graphs with two radiative photons inserted in the electron line are considered. It is demonstrated that this last gauge invariant set of diagrams which are capable of producing corrections of considered order consists of nineteen topologically different diagrams. Contributions both to HFS and Lamb shift induced by gr...
متن کاملTwo-Loop Polarization Contributions to Radiative-Recoil Corrections to Hyperfine Splitting in Muonium
We calculate radiative-recoil corrections of order α2(Zα)(m/M)EF to hyperfine splitting in muonium generated by the diagrams with electron and muon polarization loops. These corrections are enhanced by the large logarithm of the electron-muon mass ratio. The leading logarithm cubed and logarithm squared contributions were obtained a long time ago. The single-logarithmic and nonlogarithmic contr...
