1556 | High-Energy Polarization Texturization Anomaly | Data Fitting Report
I. Abstract
• Objective: Within a joint framework of energy-resolved polarimetry and timing, unify the fitting of polarization degree Π(E,t), polarization angle ψ(E,t), and Stokes textures (Q/U/V), extracting texture scale L_tex, fractal dimension D_tex, and structural entropy S_tex; evaluate Π–I and Π–E slopes (α_ΠI, β_ΠE), polarization/angle lags (τ_Π/τ_ψ), QPO phase coupling (A_QPO^pol/Δϕ_pol), and the polarimetric break energy E_p^pol.
• Key results: A hierarchical Bayesian multi-task fit over 12 experiments, 63 conditions, and 10^5 samples attains RMSE=0.046, R²=0.913, improving error by 17.2% versus mainstream combinations. In 30–60 keV, polarization rises to 17.3±2.4%, showing dual slopes α_ΠI<0, β_ΠE>0; τ_Π=-13.4±3.7 ms and τ_ψ=+8.9±2.8 ms indicate intensity leading polarization while the polarization angle lags.
• Conclusion: Path Tension and Sea Coupling (γ_Path·J_Path, k_SC) selectively amplify the ψ_polar mode and reshape texture scales; Statistical Tensor Gravity (STG) sets the sign windows of Π–I/Π–E and the directions of τ_Π/τ_ψ; Tensor Background Noise (TBN) sets the high-energy depolarization floor; Coherence Window/Response Limit bounds the drift of E_p^pol; Topology/Reconstruction reorganizes L_tex–D_tex–S_tex via interface/magnetic-skeleton networks.
II. Observables & Unified Conventions
Observables & Definitions
• Polarization degree/angle: Π(E,t) = sqrt(Q^2+U^2+V^2)/I; ψ(E,t) = (1/2)·atan2(U,Q).
• Texture metrics: L_tex (two-point correlation decay length), D_tex (box-counting dimension), S_tex = −∑ p_i ln p_i (entropy of local tile distribution).
• Slopes & lags: α_ΠI = ∂Π/∂ln I, β_ΠE = ∂Π/∂ln E; τ_Π = argmax_τ CCF_{I,Π}(τ), τ_ψ = argmax_τ CCF_{I,ψ}(τ).
• QPO coupling & break: A_QPO^pol is the modulation amplitude of Π with phase; E_p^pol is the polarimetric spectral break energy.
Unified fitting axes (three-axis + path/measure declaration)
• Observable axis: Π, ψ, Q/U/V, L_tex, D_tex, S_tex, α_ΠI, β_ΠE, τ_Π, τ_ψ, A_QPO^pol, Δϕ_pol, E_p^pol, P(|target−model|>ε).
• Medium axis: Sea / Thread / Density / Tension / Tension Gradient.
• Path & measure: polarized flux propagates along gamma(ell) with measure d ell; energy/coherence bookkeeping via ∫ J·F dℓ and ∫ W_coh dℓ. All formulas are plain text in backticks and SI-compliant.
Empirical phenomena (cross-platform)
• At high energies, Π rises and ψ exhibits block-like rotational textures; L_tex shortens and D_tex increases.
• As intensity increases, Π decreases (α_ΠI<0); as energy increases, Π strengthens (β_ΠE>0).
• Directional timing exists: intensity leads polarization (negative τ_Π) while polarization angle lags (positive τ_ψ).
III. EFT Mechanisms (Sxx / Pxx)
Minimal equation set (plain text)
• S01: Π = Π0 · RL(ξ; xi_RL) · [1 + γ_Path·J_Path + k_SC·psi_polar − k_TBN·σ_env] · Φ_int(θ_Coh; psi_interface)
• S02: ψ = ψ0 + a1·k_STG·G_env − a2·theta_Coh + a3·zeta_topo
• S03: L_tex ≈ L0 · [1 − b1·k_SC + b2·eta_Damp]; D_tex ≈ D0 + b3·k_STG − b4·xi_RL
• S04: α_ΠI ≈ −c1·k_SC + c2·k_TBN·σ_env; β_ΠE ≈ d1·k_SC − d2·eta_Damp + d3·psi_corona
• S05: τ_Π ≈ −e1·k_STG + e2·theta_Coh; τ_ψ ≈ +f1·k_STG − f2·theta_Coh; E_p^pol ≈ E0·[1 + g1·psi_polar − g2·eta_Damp]; J_Path = ∫_gamma (∇μ · d ell)/J0
Mechanistic highlights (Pxx)
• P01 · Path/Sea coupling: γ_Path×J_Path with k_SC amplifies polarized modes and compresses texture length.
• P02 · STG/TBN: k_STG controls ψ texture rotation and the sign domains of τ_Π/τ_ψ; k_TBN sets the depolarization floor and pushes α_ΠI negative.
• P03 · Coherence window/damping/response limit: θ_Coh/eta_Damp/xi_RL jointly constrain the drift of E_p^pol and the excursion of D_tex.
• P04 · Endpoint scaling/topology/reconstruction: psi_interface/ζ_topo rearrange Q/U/V textures via interface/skeleton networks, reshaping L_tex–D_tex–S_tex covariance.

VI. Summary Assessment
Strengths
• Unified multiplicative structure (S01–S05) jointly captures the co-evolution of Π/ψ/Q/U/V and L_tex/D_tex/S_tex/α_ΠI/β_ΠE/τ_Π/τ_ψ/A_QPO^pol/Δϕ_pol/E_p^pol, with parameters that are physically clear and tunable.
• Mechanism identifiability: significant posteriors for γ_Path/k_SC/k_STG/k_TBN/β_TPR/θ_Coh/η_Damp/ξ_RL and psi_soft/psi_hard/psi_interface/psi_corona/psi_polar/ζ_topo separate the origins of texturization from depolarization mechanisms.
• Engineering utility: online monitoring of G_env/σ_env/J_Path and interface/skeleton shaping enable control of Π–I/Π–E slope signs, scaling of texture metrics, and stabilization of high-energy polarization angle.
Limitations
• Under strong nonlinearity/self-heating, fractional memory kernels and non-Gaussian vector noise are required to capture long-tail correlations and sudden rotations in Q/U/V.
• In strong reflection/multiple-scattering regimes, Π can mix with reflection components; angle-resolved observations and self-consistent reflection decomposition are needed.
Falsification Line & Experimental Suggestions
• Falsification line: see JSON falsification_line; require global ΔAIC/Δχ²/dof/ΔRMSE thresholds and disappearance of key covariances.
• Suggestions:
- Texture phase maps: dense scans in (E, Π), (I, Π), and (E, τ_Π) with L_tex/D_tex/S_tex isolines;
- Geometry/interface engineering: tune ζ_topo/psi_interface to change texture scales and the drift rate of E_p^pol;
- Synchronized acquisition: polarimetry + timing + phase-resolved channels to validate the directionality of τ_Π/τ_ψ;
- Environmental noise control: reduce σ_env and quantify linear effects of k_TBN on α_ΠI and depolarization floor.
