Vacuum-polarization corrections to the parity-nonconserving 6s-7s transition amplitude in (133)Cs.

چکیده
The dominant one-loop radiative corrections to atomic wave functions, those associated with vacuum polarization in the nuclear Coulomb field, are evaluated for the 6s-7s parity-nonconserving transition amplitude in (133)Cs. These corrections increase the size of this amplitude by 0.4% and, correspondingly, increase the difference between the experimental value of the weak charge Q(W)((133)Cs) and the value predicted by the standard model.

Vacuum-Polarization Corrections to Parity-Nonconserving Effects in Atomic Systems
The dominant one-loop vacuum-polarization correction to atomic wave functions are evaluated for the 6s–7s parity nonconserving (PNC) E1 transition amplitude in cesium. This correction increases the size of the PNC amplitude by 0.4% and thus increases the difference between the experimental value of the weak charge QW and the one predicted by the standard model.

The self-energy and vertex QED radiative corrections (∼ Zα 2 f (Zα)) are shown to give a large negative contribution to the parity nonconserving (PNC) amplitude in heavy atoms. The correction −0.7(2)% found for the 6s − 7s PNC amplitude in 133 Cs brings the experimental result for this transition into agreement with the standard model. The calculations are based on a new identity that expresses...

The complete gauge-invariant set of the one-loop QED corrections to the parity-nonconserving 6s-7s amplitude in Cs is evaluated to all orders in αZ using a local version of the Dirac-Hartree-Fock potential. The calculations are peformed in both length and velocity gauges for the absorbed photon. The total binding QED correction is found to be -0.27(3)%, which differs from previous evaluations o...

I. I. Tupitsyn Institute of Physics, St. Petersburg State University, Uljanovskaya 1, Petrodvorets, 198504 St. Petersburg, Russia (Received 9 January 2001) We calculated the parity-nonconserving (PNC) 6s ! 7s amplitude in Cs. In the Dirac-Coulomb approximation our result is in good agreement with other calculations. Breit corrections to the PNC amplitude and to the Stark-induced amplitude b are...
متن کامل1 Calculations of parity nonconserving s - d transitions in Cs , Fr , Ba + , and Ra +
We have performed ab initio mixed-states and sum-overstates calculations of parity nonconserving (PNC) electric dipole (E1) transition amplitudes between s-d electron states of Cs, Fr, Ba + , and Ra +. For the lower states of these atoms we have also calculated energies, E1 transition amplitudes, and lifetimes. We have shown that PNC E1 transition amplitudes between s-d states can be calculated...
