SGCV/ALP/KM Comparison

Project Codename "Condor"

A unified simulation and analysis framework comparing three dark photon production models:

• SGCV: Superluminal Graviton Condensate Vacuum
• ALP: Axion-Like Particle scenario
• KM: Kaluza–Klein photon excitations

---

It includes Monte Carlo event generation for Higgs → γγ + γ′ decays, simplified detector geometry (ATLAS/SHiP-like), and visualization tools for analyzing spatial and temporal displacement (Δx vs Δt) distributions.

🚀 Launch on Google Colab
