The EW-$\nu_R$ model was constructed to provide a scenario in whichright-handed neutrinos are non-sterile and have masses proportional to theelectroweak scale, providing an opportunity to test the seesaw mechanism at theLHC. What was hidden in the model until recently is the chiral symmetry whichhelps solve the strong CP problem by using it to rotate $\theta_{QCD}$ to zero.It turns out the contribution from the electroweak sector to the effective$\bar{\theta}$ is proportional to the light neutrino masses and is naturallysmall, satisfying the constraint coming from the present absence of the neutronelectric dipole moment, and without the need for an axion.
