Abstract:
Searches for nonzero electric dipole moments (EDMs)
of leptons, nucleons, atoms, and molecules provide
among the most stringent limits on flavor-diagonal
T- (equivalently CP-) violating physics. I review
the current status of EDMs in the Standard Model
and the resulting constraints on the QCD vacuum
angle and CP violation from dimension-six sources
above the electroweak scale, resulting from for
instance supersymmetry. I discuss recent progress
to classify these sources and to formulate strategies
to disentangle them from hadronic EDMs by using
chiral effective field theory. Finally, an outlook
is given on this very active field.
