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 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…
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…
