# Dependence of atomic parity-violation effects on neutron skins and new physics

@article{Viatkina2019DependenceOA, title={Dependence of atomic parity-violation effects on neutron skins and new physics}, author={A. V. Viatkina and Dionysios Antypas and Mikhail G. Kozlov and Dmitry Budker and Victor V. Flambaum}, journal={Physical Review C}, year={2019} }

We estimate the relative contribution of nuclear structure and new physics couplings to the parity non-conserving spin-independent effects in atomic systems, for both single isotopes and isotopic ratios. General expressions are presented to assess the sensitivity of isotopic ratios to neutron skins and to couplings beyond standard model at tree level. The specific coefficients for these contributions are calculated assuming Fermi distribution for proton and neutron nuclear densities for…
