The Standard Model in Strong Fields: Electroweak Radiative Corrections for Highly Charged Ions

I. Bednyakov, L. Labzowsky, G. Plunien, G. Soff, V. Karasiev

abstract: Electroweak radiative corrections to the matrix elements $$ are calculated for highly charged hydrogenlike ions. These matrix elements constitute the basis for the description of the most parity nonconserving (PNC) processes in atomic physics. The operator ${\hat H}_{PNC}$ represents the parity nonconserving relativistic effective atomic Hamiltonian at the tree level. The deviation of these calculations from the calculations valid for the momentum transfer $q^{2}=0$ demonstrates the effect of the strong field, characterized by the momentum transfer $q^{2}=m_{e}^{2}$ ($m_{e}$ is the electron mass). This allows for a test of the Standard Model in the presence of strong fields in experiments with highly charged ions.
