Φ-Trend Mapping of Antiproton Spin Coherence: A Theory of Everything Prediction Confirmed by 2021–2025 BASE Data

Description: This work presents the Φ-trend curve derived from the Theory of Everything (ToE) framework, describing the intrinsic relationship between spin coherence time, resonance linewidth, and spectroscopy signal contrast in single (anti)proton experiments. Remarkably, the Φ-trend was mathematically formulated before the release of the most recent CERN BASE experimental results (2021–2025), yet all published milestones fall precisely on the predicted curve without calibration or iterative optimization.We provide a complete theoretical–experimental synthesis, a graphical overlay of BASE data versus Φ-trend predictions, and the forecast of the next achievable regime — τₛ ≈ 250 s, Δν_FWHM ≈ 31 mHz, S ≥ 0.90 — attainable with current apparatus. This demonstrates that precision milestones in antimatter spin spectroscopy follow a universal resonant-damping structure, enabling a direct leap to the theoretical endpoint in a single measurement campaign.
