TL;DR
This paper derives upper bounds on the electric dipole moments of the tau-lepton, heavy quarks, and W-boson based on precision measurements of electron and neutron EDMs, constraining new physics models.
Contribution
It provides new limits on EDMs of heavy particles using indirect measurements, extending constraints on CP violation beyond previous direct searches.
Findings
Upper limits on tau-lepton EDM
Constraints on heavy quark EDMs
Bounds on W-boson EDM
Abstract
We discuss upper limits on the electric dipole moments (EDM) of the tau-lepton, heavy quarks, and W-boson, which follow from the precision measurements of the electron and neutron EDM.
