A Unified Mass Prediction for the Scalar Glueball (0++) via Lattice QCD and Closed-String Symmetry

Update (August 2026): This version includes new sections detailing the Empirical Quantum Verifications simulated via VQE, QPE, and Hamiltonian Dynamics on Qiskit/IBM Quantum architectures. Source codes are open-source.The existence of a mass gap in Yang-Mills theory and the experimental detection of glueballs remain outstanding challenges. In this paper, we present a unified, falsifiable prediction for the mass of the fundamental scalar glueball (0++) by intersecting numerical results from Lattice QCD with the exact topological restriction of the Ouroboros model. Formal Verification & Source Code: The rigorous Lean 4 proofs and framework codebase are open-source and available at the Ouroboros GitHub Repository.
