The Electric Dipole Form Factor of the Nucleon in Chiral Perturbation Theory to Sub-leading Order
E. Mereghetti, J. de Vries, W. H. Hockings +2
The electric dipole form factor (EDFF) of the nucleon stemming from the QCD theta term and from the quark color-electric dipole moments is calculated in chiral perturbation theory…

The Effective Chiral Lagrangian From the Theta Term
E. Mereghetti, W. H. Hockings, U. van Kolck
We construct the effective chiral Lagrangian involving hadronic and electromagnetic interactions originating from the QCD theta term. We impose vacuum alignment at both quark and h…
