High quality Nelson-Barr solution to the strong CP problem with θ = π

Gilad Perez et al.

Summary: This paper discusses composite UV completions of the Nelson-Barr solution to the strong CP problem, focusing on the minimal implementation which includes an extra pair of vector-like up/down quarks in the visible sector. The minimal NB theory is shown to have a quality problem, and a simple calculable scheme is presented to resolve this issue through a scalar portal mediating dynamical CP violation in the hidden sector to the visible sector.

Super-soft CP violation

Alessandro Valenti et al.

Summary: The solution of the Strong CP Problem is based on the spontaneous breaking of CP, requiring a non-generic structure to explain a coincidence between CP-even and CP-odd mass scales. This approach, utilizing gauge invariance and a CP-conserving physics at the Planck scale, predicts a dark sector with potential cosmological signatures.

Complete solution to the strong CP problem: Supersymmetric extension of the Nelson-Barr model

Jason L. Evans et al.

Summary: This paper presents a supersymmetric solution to the strong CP problem based on spontaneous CP violation, which also addresses the effects of supersymmetry breaking. The problematic phases in supersymmetry breaking parameters are suppressed by a specific gauge mediation model, allowing for a complete and consistent solution. The generated CP violating phase in the neutrino sector can potentially lead to the baryon asymmetry of the universe through leptogeneis.
