Abstract: (arXiv)

Electroweak radiative corrections to the matrix elements

<ns_{1/2}|{\hat H}_{PNC}|n'p_{1/2}>

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.
