Abstract

Supersymmetric loop corrections induce potentially large [Formula presented]-violating couplings of the Higgs bosons to nucleons and electrons that do not vanish in the limit of heavy superpartners. The Higgs-mediated [Formula presented]-odd four-fermion operators are enhanced by [Formula presented] and induce electric dipole moments of heavy atoms which exceed the current experimental bounds for the electroweak scale Higgs masses and [Formula presented]. If only the first two sfermion generations are heavy, the Higgs-mediated contributions typically dominate over the Barr-Zee type two-loop diagrams at [Formula presented].
