Particle Physics Data + +This module implements the Riemannian Resonance Correlator (RRC): +a mathematical tool for extracting generating structures from 50 years +of particle physics event data. + +The pipeline: + 1. Ingest measured observables (J_i, cross sections, branching ratios) + 2. Embed in Riemannian manifold (event space with natural metric) + 3. Extract resonance patterns (eigenmodes of the Laplacian) + 4. Learn the kernel K that generates observed distributions + 5.
