Atomic parity violation in highly charged 40,48Ca and 208Pb ions — •Anna Viatkina1,2, Christopher Mertens3, Ben Ohayon4, Vladimir Yerokhin5, and Andrey Surzhykov1,2 — 1Technische Universität Braunschweig, 38106 Braunschweig, Germany — 2Physikalisch-Technische Bundesanstalt, 38116 Braunschweig, Germany — 3Rheinisch-Westfälische Technische Hochschule Aachen, 52062 Aachen, Germany — 4Technion-Israel Institute of Technology, Haifa 3200003, Israel — 5Max-Planck-Institut für Kernphysik, 69117 Heidelberg, Germany
We calculate parity-violation-induced E1 amplitudes for the 1s→ 2s and 1s2 2s→ 1s2 3s transitions in H- and Li-like ions of 40Ca, 48Ca, and 208Pb; neutron skin effects and nuclear uncertainties are included for each nucleus. We consider spin-independent weak-interaction contribution of the Z0 boson described by standard model, as well as the effects of a hypothetical new Z′ boson of varying mass. We conclude that the neutron-skin corrections in the 40,48Ca isotope pair can be mostly neglected when considering Z′ boson effects, which is an advantage for the search for new parity-violating physics. On the other hand, both the neutron skin effect and the sensitivity to hypothetical Z′ interactions in 208Pb is shown to be significant.
