Nelson-Barr models with vector-like quark doublets suppress hadronic CP violation to three loops via an accidental symmetry in the renormalizable theory, yielding phenomenologically viable solutions distinct from singlet-based models.

abstract
We propose a new solution to the strong CP problem based on supersymmetric non-renormalization theorems. CP is broken spontaneously and it's breaking is communicated to the MSSM by radiative corrections. The strong CP phase is protected by a susy non-renormalization theorem and remains exactly zero while loops can generate a large CKM phase from wave function renormalization. We present a concrete model as an example but stress that our framework is general. We also discuss constraints on susy breaking and point out experimental signatures.

A new scalar induces transient bias to decay CP domain walls from spontaneous CP violation while its oscillations constitute dark matter.
Spontaneous CP violation is realized in SUSY via an extended spurion formalism in the exact limit and a model with intermediate-scale breaking along pseudo-flat directions stabilized by soft terms and non-perturbative gauge effects, predicting light scalars.
