Query: EFT approach to the electron Electric Dipole Moment at the two-loop
  level   The ACME collaboration has recently reported a new bound on the electric
dipole moment (EDM) of the electron, $|d_e|< 1.1 \times 10^{-29}\, {\rm e\cdot
cm}$ at 90$\%$ confidence level, reaching an unprecedented accuracy level. This
can translate into new relevant constraints on theories beyond the SM laying at
the TeV scale, even when they contribute to the electron EDM at the two-loop
level. We use the EFT approach to classify these corrections, presenting the
contributions to the anomalous dimension of the CP-violating dipole operators
of the electron up to the two-loop level. Selection rules based on helicity and
CP play an important role to simplify this analysis. We use this result to
provide new bounds on BSM with leptoquarks, extra Higgs, or constraints in
sectors of the MSSM and composite Higgs models. The new ACME bound pushes
natural theories significantly more into fine-tune territory, unless they have
a way to accidentally preserve CP.
