Vacuum Polarization Effects in Relativistic Nuclear Pairing
In the present work we discuss the contribution of the vacuum polarization on the nuclear pairing, in the context of the relativistic Hartree-Fock-Bogoliubov (HFB) approximation. The polarization effects on the pairing, as a function of Fermi momentum, is shown with the scalar and vector meson-nucleon coupling constants scaled by a parameter x. We have obtained that the nuclear pairing is affec...
متن کاملVacuum polarization in muonic atoms: the Lamb shift at low and medium Z
In muonic atoms the Uehling potential (an effect of a free electronic vacuum polarization loop) is responsible for the leading contribution to the Lamb shift causing the splitting of states with ∆n = 0 and ∆l 6= 0. Here we consider the Lamb shift in the leading nonrelativistic approximation, i.e., within an approach based on a certain Schrödinger equation. That is valid for low and medium Z as ...
متن کاملVacuum polarization in muonic and antiprotonic atoms : the fine structure at medium Z
Effects of vacuum polarization modify the energy levels in atoms with an orbiting particle heavier than an electron. The dominant effect is due to the Uehling potential. In this paper we consider the relativistic corrections to the energy levels caused by the Uehling potential and in particular the fine structure in muonic and antiprotonic atoms. We derive general expressions and consider in de...
متن کاملPadé-Approximation to the α Vacuum-Polarization Function and the Lamb Shift of the Muonic Hydrogen
The contribution of the α3 single electron-loop vacuum-polarization diagrams to the Lamb shift of the muonic hydrogen has been evaluated recently by two methods. One uses the exact parametric representation of the vacuum-polarization function while the other relies on the Padé approximation method. High numerical precision of these calculations enables us to examine the accuracy of the Monte-Ca...
متن کاملContribution of Hadronic Vacuum Polarization to Hyperfine Splitting of Muonic Hydrogen
The contribution of hadronic vacuum polarization to the hyperfine splitting of the muonic hydrogen ground state is calculated with the account of experimental data on the cross section of e+e− → annihilation into hadrons and the dipole parameterization of electromagnetic proton form factors.
