Relative enhancement of low-mass vector-boson exchange in higher waves matrix elements: parity non-conservation in hydrogen
V. A. Dzuba, V. V. Flambaum, G. K. Vong
Models of unification predict additional boson, which contributes to parity non-conservation (PNC) in atoms. If boson is light, ratio of boson contribution to the St…
Parity non-conservation in isotope chain of tin
V. A. Dzuba, V. V. Flambaum, D. DeMille +2
We calculate parity non-conservation (PNC) amplitudes for all magnetic-dipole (M1) transitions within the ground configuration of Sn, including the standard model interactio…
Shielded inner-shell transitions in atomic samarium for tests of fundamental physics
R. Aramyan, D. Budker, V. A. Dzuba +5
Forbidden atomic transitions provide some of the most stringent low-energy tests of physics beyond the Standard Model, with sensitivity set by the interplay between the sought-for…
Parity Nonconservation in Rb and Sr due to Low-Mass Vector Boson
V. A. Dzuba, V. V. Flambaum, G. K. Vong
We calculate the parity non-conserving (PNC) electric-dipole () transition amplitudes for the and transitions in Rb and Sr. Our results include bo…
Parity Nonconservation in Hydrogen Induced by Low-Mass Vector-Boson Exchange
V. A. Dzuba, V. V. Flambaum, G. K. Vong
Parity-nonconserving (PNC) effects in atoms produced by -boson exchange between the electron and the nucleus grow rapidly with the nuclear charge . If a hypothetical addition…
Hf ion: Highly Charged Ion for Next-Generation Atomic Clocks and Tests of Fundamental Physics
Saleh O. Allehabi, V. A. Dzuba, V. V. Flambaum
We use advanced computational techniques to study the electronic structure of the Hf ion, with the goal of assessing its potential for use in highly accurate atomic optical…
