# Improved limits on the hardronic and semihadronic CP violating parameters and role of a dark force carrier in the electric dipole moment of 199Hg

@article{Sahoo2017ImprovedLO, title={Improved limits on the hardronic and semihadronic CP violating parameters and role of a dark force carrier in the electric dipole moment of 199Hg}, author={Bijaya Kumar Sahoo}, journal={Physical Review D}, year={2017}, volume={95}, pages={013002} }

Combining the recently reported electric dipole moment (EDM) of the $^{199}\mathrm{Hg}$ atom due to breaking of parity and time-reversal symmetries with the improved relativistic atomic calculations, precise limits on the tensor-pseudotensor (T-PT) electron-nucleus (e-N) coupling coefficient and the nuclear Schiff moment interactions are determined. Using these limits with the nuclear calculations, we infer limits on the EDMs of the neutron and proton as ${d}_{n}l2.2\ifmmode\times\else…
