Weak long distance contributions to the neutron and proton electric dipole moments

We evaluate the long distance weak contribution to the neutron and proton electric dipole moments using an effective Lagrangian framework. We estimate the coefficients needed by a factorization hypothesis and additional assumptions on γ5 terms in the baryon lagrangian. We obtain |den| ≈ 5 × 10−32 e·cm and |dep| ≈ 4 × 10−32 e·cm. The former estimate is similar to the quark model estimates done previously.
