Three-Loop Reducible Radiative Photon Contributions to Lamb Shift and Hyperfine Splitting
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 کاملRadiative-Recoil Corrections of Order α(Zα)(m/M)m to Lamb Shift Revisited
The results and main steps of an analytic calculation of radiative-recoil corrections of order α(Zα)5(m/M)m to the Lamb shift in hydrogen are presented. The calculations are performed in the infrared safe Yennie gauge. The discrepancy between two previous numerical calculations of these corrections existing in the literature is resolved. Our new result eliminates the largest source of the theor...
متن کاملLamb Shift in Muonic Hydrogen
The Lamb shift in muonic hydrogen continues to be a subject of experimental and theoretical investigation. Here my older work on the subject is updated to provide a complementary calculation of the energies of the 2p-2s transitions in muonic hydrogen. Introduction The energy levels of muonic atoms are very sensitive to effects of quantum electrodynamics (QED), nuclear structure, and recoil, sin...
متن کاملThe Lamb Shift in Dimensional Regularisation
We present a simple derivation of the Lamb shift using effective field theory techniques and dimensional regularisation.
متن کاملThe Lamb Shift Experiment in Muonic Hydrogen
The subject of this thesis is the muonic hydrogen (μ−p) Lamb shift experiment being performed at the Paul Scherrer Institute, Switzerland. Its goal is to measure the 2S − 2P energy difference in μp atoms by laser spectroscopy and to deduce the proton root–mean– square (rms) charge radius rp with 10 −3 precision, an order of magnitude better than presently known. This would make it possible to t...
