Neutron electric dipole moment: Constituent dressing and compositeness

Contributions to the neutron's electric dipole moment (EDM), d{sub n}, are calculated using a well-constrained ansatz for the nucleon's Poincare covariant Fadde'ev amplitude. The momentum-dependent quark dressing amplifies the contribution from the current-quarks' EDMs; and dressed-quark confinement and binding make distinguishable the effect of the two CP and T violating interactions: i{gamma}{sub 5}{sigma}{sub {mu}{nu}}(p{sub 1}-p{sub 2}){sub {nu}} and {gamma}{sub 5}(p{sub 1}+p{sub 2}){sub {mu}}, where p{sub 1,2} are the current-quarks' momenta. The value of |d{sub n}| obtained using the current-quark EDMs generated by a minimal three Higgs doublet model of spontaneous CP violation is close to the current experimental upper bound.
