Strong CP Problem in Type IIA Toroidal Orientifold String Theory

We present a globally consistent Type IIA $T^6/(\mathbb{Z}_2 \times \mathbb{Z}_2)$ orientifold with intersecting D6-branes that dynamically solves the strong CP problem via the four-form flux mechanism. The construction satisfies all RR tadpole, K-theory, and SUSY conditions, stabilizes all moduli, and uplifts to dS va...
