Description
The most well-known solutions to the Strong CP problem are arguably axion and Nelson-Barr models. A much lesser known class of solutions involves a simple extension of scalar sector of the Standard Model by at least one additional Higgs doublet. I review my recent work with Professor Hall, in which we develop a mechanism by which a combination of CP and flavor symmetry can simultaneously reproduce the masses, mixings, and CP-violating phase of the CKM matrix while giving sufficiently small contributions to $\bar\theta$ that are stable to radiative corrections.
