Large long-distance contributions to the electric dipole moments of charged leptons in the standard model

Yamaguchi, Yasuhiro ; Yamanaka, Nodoka*

We reevaluate the electric dipole moment (EDM) of charged leptons in the standard model using hadron effective models. We find unexpectedly large EDM generated by the hadron level long-distance effect, $d_e = 5.8times 10^{-40}$ , $d_{mu} = 1.4times 10^{-38}$ , and $d_{tau}= -7.3times 10^{-38}$ cm, with an error bar of 70%, exceeding the conventionally known four-loop level elementary contribution by several orders of magnitude.
