预处理流程

  1. 统一校准：能标/角分辨/效率校正；
  2. 变点检测：对 θ_F 扫描用变点+二阶导识别门控带边界，估计 W_gate、θ_gate、σ_θ；
  3. b 空间全局拟合：并行拟合 g2_NP、⟨k_T²⟩_{q,g}；
  4. 多任务联合：以 SIDIS/DY/WZ/γ–Jet/e⁺e⁻ 的振幅/谱形联合反演 {k_gate, ψ_field, ψ_spin, k_STG, zeta_topo}；
  5. 误差传递：total_least_squares + errors-in-variables 统一能标/角度/触发；
  6. 分层贝叶斯（MCMC）：按过程/能区/极化层级共享先验，R̂<1.05 与 IAT 判收敛；
  7. 稳健性：k=5 交叉验证与按过程留一法。

VI. 总结性评价
优势

  1. 统一乘性结构（S01–S05） 将外场取向、极化、TMD 宽度与非微扰 Sudakov 的作用纳入同一可辨框架，参数物理含义明确，可指导 外场角/极化扫描、能区与过程选择、b 空间正则与实验触发策略。
  2. 机理可辨识：k_gate/ψ_field/ψ_spin/γ_Path/k_SC/k_STG/zeta_topo/g2_NP/⟨k_T²⟩ 后验显著，区分取向门控与纯 CSS/SCET 的差异来源。
  3. 工程可用：给出 (θ_F,φ_F) 的门控相图与 A_aniso 预算，支持台站布置与统计功效评估。

盲区

  1. 低 Q 与高 P_T 尾部可能出现 g2_NP 与 ⟨k_T²⟩ 的共线性，需更多 Q 分层以解耦；
  2. 部分 DY 数据在前向区受 UE/极化系统学影响较大，k_TBN 估计仍有改进空间。

证伪线与实验建议

  1. 证伪线：当上表 EFT 参量 → 0 且 W_gate、A_aniso、ΔA_N(SIDIS−DY) 的协变关系消失，同时标准 CSS/SCET（无门控项）在全域满足 ΔAIC<2、Δχ²/dof<0.02、ΔRMSE≤1%，则本机制被否证。
  2. 实验建议：
    • 二维相图：绘制 (θ_F,φ_F) 与 (Q,P_T) 上的门控带与 A_aniso；
    • 号变检验：在相同 (x,Q) 条件下并行 SIDIS/DY 测量，精确约束 ΔA_N；
    • b 空间正则：扩展大 b 区数据以收紧 g2_NP；
    • 拓扑诊断：通过 jet–hadron 相关与 \u0394\u03c6 扫描，定量评估 zeta_topo 对外环增厚的影响。
