Abstract
In this paper we study the contribution of a dimension-six four-quark operator to the neutron electric dipole moment. We find that this contribution dominates over the one-loop contributions due to WL-WR mixing by at least one order of magnitude in left-right-symmetric models, and in diquark scalar models this contribution is two orders of magnitude larger than other contributions. © 1993 The American Physical Society.
