Parity Nonconservation in Rb and Sr$^+$ due to Low-Mass Vector Boson

G. K. Vong, V. A. Dzuba, V. V. Flambaum

In rubidium and strontium ions, the relative contribution of a low-mass Z' boson to parity violation grows rapidly with decreasing nuclear charge.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The ratio of the contribution of a low mass Z'-boson to the contribution of the Standard model Z-boson to PNC effects increases rapidly (faster than 1/Z^2) with decreasing nuclear charge Z.

C2weakest assumption

The hypothetical low-mass Z' boson exists and couples to electrons and nucleons in a manner that produces an additional parity-violating interaction whose strength and range are not constrained by other data.

C3one line summary

The relative contribution of a hypothetical low-mass Z' boson to parity nonconservation in Rb and Sr+ increases faster than 1/Z² with decreasing nuclear charge Z, highlighting advantages of light atoms for new physics searches.
