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.

Abstract

The QCD vacuum angle θₚhys = θQCD + arg (det Mq) is shown to be exactly zero within the UFFT framework. θQCD = 0 from the torsion potential ground state V (θ) = k (1 − cos θ). arg (det Mq) = 0 from the Hermiticity of the torsion Hamiltonian. No axion, no new symmetry, no fine-tuning. Predictions: no axion detection, neutron EDM exactly zero.
