TDG/TQ Pre-Data Predictions for the 2025 LHC Pb--Pb Campaign

TDG/TQ Pre-Data Predictions for the 2025 LHC Pb–Pb Campaign Parameter-Locked Forecasts with Methods, Deviations, and Reference Geometry Johnny Rouse (Rouse Nexus LLC) November 6, 2025 Abstract This record lists pre-data, parameter-free predictions from the Time-Dilation Geometry / Timeless Quanta (TDG/TQ) framework for key Pb–Pb observables targeted by ALICE, CMS, ATLAS, and LHCb during the 2025 heavy-ion campaign. Each prediction is accompanied by its baseline comparator (hydrodynamics, pQCD, or clustering), method, numerical value, deviation, and geometric lock. No post-run adjustments will be made. All constants, curvature thresholds, and scaling laws originate from the companion theoretical work [1]. Artificial intelligence tools were used solely to assist in document structuring, LaTeX formatting, and reference consistency checks; all scientific reasoning and derivations are the author’s. Reference Geometry and Core Framework All scaling laws, curvature thresholds, and normalization constants used here are defined in detail in the companion theoretical paper: J. Rouse, Timeless Quanta: A Threshold Geometry for Mass, Entropy, and Time (Version 3.0, 2025), Zenodo, DOI: 10.5281/zenodo.14693026. That paper establishes the single geometric lock: rc= 0.447 fm,Θc= 1.62 ×1038 m−2, K =−1.93 ×1047, which remain fixed for all Pb–Pb predictions below. 1 Prediction Table (Baselines, Methods, Deviations, Lock-In) Collab.
