Validated Dataset: Polynomial Surrogate for Benchmark Gauge-Coupling Running and Unification Diagnostics

Supplementary validated numerical dataset accompanying the preprint A Polynomial Surrogate for Benchmark Gauge-Coupling Running and Unification Diagnostics by Ali Al-Rubaidi (2026).The preprint is available on ResearchGate: https://www.researchgate.net/publication/402698745_A_Polynomial_Surrogate_for_Benchmark_Gauge-Coupling_Running_and_Unication_DiagnosticsComments, feedback, and suggestions from the community are welcome.Contains:(1) Polynomial fits for electromagnetic, weak, and strong couplings with Vieta coefficients and discriminants (validated_coupling_data.json)(2) One-loop RG evolution tables for Standard Model (rg_evolution_sm.csv) and MSSM (rg_evolution_mssm.csv)(3) Interpolation accuracy benchmarks: log-linear surrogate vs constant-b0 one-loop RG (interpolation_accuracy.csv)(4) Threshold-matched benchmark: surrogate vs piecewise one-loop and two-loop QED running with fermion mass thresholds (threshold_benchmark.csv)(5) Complete validation report with all corrections applied (VALIDATION_REPORT.md)Version 2.0 incorporates corrected delta arithmetic (0.0102), threshold comparison table, strong coupling uncertainty bounds, and updated bibliography references.
