Special embedding of the composite axion and QCD gauge groups into a larger product gauge group reduces the domain wall number to unity and induces a controlled bias term from UV instantons that destabilizes the walls.
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.
