Abstract
In this paper we study the neutron electric dipole moment due to Higgs-boson exchange in left-right-symmetric models. In pseudomanifest left-right-symmetric models, the neutral Higgs contribution is smaller than that from the charged Higgs boson. The charged-Higgs-contribution at the two-loop level can be as large as the experimental upper bound. In non(pseudo)manifest left-right-symmteric models, the neutral-Higgs-boson exchange contribution can reach the experimental upper bound. The Higgs-boson exchange contributions can be more important than the ones from W-boson exchange due to WL-WR mixing. © 1992 The American Physical Society.
