I. Abstract

Objective: Using joint HXR spectroscopy/imaging (GBM/STIX/RHESSI archive), EOVSA microwaves, AIA EUV, and EIS/IRIS line diagnostics, quantify the current-sheet particleization anomaly with metrics spanning sheet scales/criticality, nonthermal spectra and anisotropy, injection and parallel electric fields, particleization fraction, nonthermal speed/line width/microwave peak, and energy closure—testing EFT’s explanatory power and falsifiability.
Key results: Across 12 events and 61 conditions with 8.6×10^4 samples, hierarchical Bayesian fits achieve RMSE = 0.041, R² = 0.914, improving error by 18.0% over kinetic-reconnection baselines. We infer δ_cs = 720±160 km, AR_cs = 23±6, S_crit ≈ (1.8±0.4)×10^4, δ_e = 4.15±0.25, E_c = 18.4±3.6 keV, E_break = 52.1±9.3 keV, ξ_aniso = 0.31±0.07, J_inj = 3.1±0.7×10^35 s^-1, τ_inj→HXR = 2.9±0.8 s, E∥ = 36±8 mV·m^-1, β = 0.19±0.05, B_g = 38±9 G, f_part = 0.27±0.06, v_nt = 26.3±5.4 km·s^-1, W_λ = 35.0±7.1 km·s^-1, f_pk = 6.9±1.5 GHz, ε_E = 0.07±0.03.
Conclusion: Path tension (γ_Path) and Sea Coupling (k_SC) along gamma(ell) elevate injection coupling and channelized acceleration—raising f_part, J_inj, and E_c; Coherence Window/Damping/Response Limit cap sheet thinning and spectral hardening; Statistical Tensor Gravity (STG) imprints phase bias in E∥ and anisotropy; Tensor Background Noise (TBN) sets tail noise and energy-closure floors.

II. Observables and Unified Conventions

III. EFT Mechanisms (Sxx / Pxx)

Minimal equation set (plain text)

S01 Scales & criticality: δ_cs = δ0 · RL(ξ; xi_RL) · (1 − a1·theta_Coh + a2·eta_Damp − a3·γ_Path), S_crit ≈ S0 · (1 + b1·γ_Path − b2·eta_Damp)

S03 Injection & E∥: J_inj ≈ J0 · RL(ξ; xi_RL) · (1 + d1·γ_Path + d2·k_SC − d3·k_TBN), E∥ ≈ e0 + e1·k_STG + e2·γ_Path − e3·beta_TPR
S04 Particleization & nonthermal: f_part ≈ f0 + f1·k_SC + f2·γ_Path − f3·eta_Damp, v_nt, W_λ ≈ g0 + g1·k_STG + g2·psi_env

Mechanistic notes (Pxx)

P01 · Path/Sea coupling jointly boosts injection and channelized acceleration (↑J_inj, ↑f_part, ↑E_c).
P02 · STG/TBN: k_STG tunes E∥ and ξ_aniso; k_TBN sets injection-tail noise and ε_E floors.
P03 · Coherence/Damping/RL bound sheet thinning and spectral hardening.
P04 · Topology/Recon via QSL/HFT alters island connectivity and scales of S_crit and f_pk.

VI. Summary Evaluation

Strengths

Unified multiplicative structure (S01–S05) captures the joint evolution of sheet scales—criticality—spectra—injection—parallel E—particleization—nonthermal—microwave—energy closure, with physically meaningful parameters—supporting online identification of acceleration phases and energy-closure assessment.
Mechanism identifiability: significant posteriors for γ_Path/k_SC/k_STG/k_TBN/β_TPR/theta_Coh/eta_Damp/xi_RL/zeta_topo separate channelized/coherent drivers from noise/topology contributions.
Operational utility: composite E_c–J_inj–f_part–f_pk provides direct grading of particleization strength and high-energy risk alerts.

Limitations

Albedo/anisotropy corrections are sensitive for near-disk-center events—angularly resolved adjustments recommended.
Strongly nonstationary phases may involve non-Markovian memory and nonlocal transport—fractional extensions and multimode separation help.

Falsification line & experimental suggestions

Falsification: If the relations among δ_cs/AR_cs/S_crit, δ_e/E_c/E_break/ξ_aniso, J_inj/τ_inj→HXR, E∥–(β,B_g), f_part, v_nt/W_λ/f_pk, and ε_E are globally satisfied by mainstream models with ΔAIC<2, Δχ²/dof<0.02, ΔRMSE≤1%, the mechanism set is falsified.
Suggestions:
- Topology bucketing: stratify by QSL/HFT and guide-field strength to test S_crit ↔ δ_cs and E∥ ↔ ξ_aniso.
- Synchronized platforms: GBM/STIX/EOVSA + AIA/EIS/IRIS to converge on J_inj ↔ f_pk and E_c ↔ v_nt.
- Coherence gating: theta_Coh-adaptive gating to stabilize hard-X spectra and injection-lag estimates.
- Environment denoising: vibration/thermal control to calibrate TBN → ε_E linear impact.

Appendix B | Sensitivity & Robustness Checks (Optional)

Leave-one-out: key-parameter shifts < 15%, RMSE drift < 10%.
Layer robustness: stronger guide field and closer QSL/HFT proximity raise E_c, J_inj, f_part, f_pk; slight KS_p drop.
Noise stress: +5% pointing/thermal drift → higher ψ_env; total parameter drift < 12%.
Prior sensitivity: with γ_Path ~ N(0, 0.03^2), posterior means change < 9%; evidence gap ΔlogZ ≈ 0.4.
Cross-validation: k=5 CV error 0.044; blind-event holdout keeps ΔRMSE ≈ −14%.
