DESCRIPTION:Speakers: Naohiro Osamura ()\nThis talk studies a three-loop c
 ontribution to the electron EDM induced by CP-violating Yukawa couplings o
 f new $SU(2)_L$ multiplets.\nThese couplings generate the electroweak Wein
 berg operator at two loops\, whose one-loop insertion can yield an electro
 n EDM larger than the SM contribution even for TeV-scale new particles.\nT
 he paper also compares this three-loop effect with the usual two-loop Barr
 –Zee contribution when the SM Higgs has new Yukawa interactions.\n\nhttp
