Nuclear Structure-Dependent Radiative Corrections to the Hydrogen Hyperfine Splitting
نویسنده
چکیده
Radiative corrections to the Zemach contribution of the hydrogen hyperfine splitting are calculated. Their contributions amount to −0.63(3) ppm to the HFS. The radiative recoil corrections are estimated to be 0.09(3) ppm and heavy particle vacuum polarization shifts the HFS by 0.10(2) ppm. The status of the nuclear-dependent contributions are considered. From the comparison of theory and experiment the proton polarizability contribution of 3.5(9) ppm is found. The nuclear structure-dependent corrections to the difference νhfs(1s)− n 3 νhfs(ns) are also obtained.

Three-Loop Radiative-Recoil Corrections to Hyperfine Splitting Generated by One-Loop Fermion Factors
We consider three-loop radiative-recoil corrections to hyperfine splitting in muonium generated by diagrams with one-loop radiative photon insertions both in the electron and muon lines. An analytic result for these nonlogarithmic corrections of order α(Zα)(Zα)(m/M)ẼF is obtained. This result constitutes a next step in the implementation of the program of reduction of the theoretical uncertaint...
متن کاملQuantum electrodynamic corrections to the hyperfine structure of excited S states
State-dependent quantum electrodynamic corrections are evaluated for the hyperfine splitting of nS states for arbitrary principal quantum number n. The calculations comprise both the self-energy and the vacuumpolarization correction of order α (Z α) EF and the recoil correction of order (Z α) (m/M)EF . Higherorder corrections are summarized and partly reevaluated as well. Accurate predictions f...
متن کاملSpin Dependent Nucleon Structure at Intermediate Q
This thesis focuses on hadronic spin structure at low and intermediate energies, 0 < Q2 < 3 GeV 2. The thesis is divided into two main sections. Each section addresses a different aspect of spin dependent hadronic physics which has not been studied previously in detail. The first section studies hydrogen hyperfine splitting. A polarizability term depending on the proton's G1 and G2 spin depende...
متن کاملThree-Loop Radiative-Recoil Corrections to Hyperfine Splitting in Muonium
We calculate three-loop radiative-recoil corrections to hyperfine splitting in muonium generated by the diagrams with the first order electron and muon polarization loop insertions in graphs with two exchanged photons. These corrections are enhanced by the large logarithm of the electron-muon mass ratio. The leading logarithm squared contribution was obtained a long time ago. Here we calculate ...
