Abstract

In this Bachelor thesis the energy shift in atoms due to hadronic vacuum polarization is evaluated. A hadronic polarization function for the photon propagator is obtained from experimental e^-/ e⁺ → hadronic matter-collision data via the optical theorem and the Kramers-Kronig relations. An effective central potential is calculated applying a parameterization for this polarization function. The energy corrections to a Coulomb potential originating from hadronic vacuum polarization are calculated using the analytical bound Dirac-Coulomb wave functions, as well as relativistic bound wave functions considering the finite nuclear size. These results are compared to results from a non-relativistic theory.
