摘要：
The dominant contribution to the neutron electric dipole moment from Higgs exchange comes from a three-gluon operator, produced by integrating out top quarks and neutral Higgs bosons. We calculate one-loop QCD corrections to this operator. Comparing the result to current experimental limits on dn gives very strong constraints on CP violation in the Higgs sector. © 1990.
