The Strong CP Problem Dissolved by Foam Torsion Dynamics

Key Points

• To resolve the strong CP problem by showing that the QCD vacuum angle is exactly zero.
• Utilized the UFFT framework to analyze the QCD vacuum angle.
• Examined the torsion potential ground state V(θ) for implications on θ_phys.
• Demonstrated that arg(det M_q) equals zero due to the Hermiticity of the torsion Hamiltonian.
• Confirmed that the QCD vacuum angle θ_phys is zero.
• Predicted no detection of axions or neutron electric dipole moment (EDM) as a result.
• Established that no new symmetries or fine-tuning are required.
