Octonionic Unification: A Geometric Theory of Particle Masses and Dark Matter

Octonionic Unification: A Geometric Theory of Particle Masses and Dark Matter This work presents a novel theoretical framework for particle physics based on octonionic algebra that unifies mass generation, quantum corrections, and dark matter within a single geometric structure. The theory achieves remarkable predictive power with zero adjustable parameters. **Key Results:** 1. **Mass Predictions (94% accuracy)**: Tree-level predictions for all Standard Model fermion and gauge boson masses achieve 94% accuracy using only geometric principles from octonionic algebra, compared to the Standard Model's 19 free parameters. Leptons are predicted to within 1% accuracy, with W and Z boson masses exact to experimental precision. 2. **Quantum Corrections**: A geometric torsion-based formula successfully predicts the long-standing muon g-2 anomaly (221 × 10⁻¹¹ vs. observed 230 ± 72 × 10⁻¹¹), within 1σ agreement. The theory also predicts the unmeasured tau lepton g-2 = 3.91 × 10⁻⁷. 3. **Dark Matter Identification**: The framework naturally identifies dark matter with unfilled modes in octonionic space, predicting: - Dark matter fraction: 83% (observed: 85%, error < 2%) - Cosmological mass ratio Ω_DM/Ω_visible = 5.0 (observed: 5.39 ± 0.14, error 7%) - Common mass scale near electroweak symmetry breaking (~200-300 GeV) 4. **Unique Experimental Signatures**: Unlike typical dark matter models spanning wide mass ranges, this theory predicts multiple dark matter species clustered at similar masses near the electroweak scale, providing highly focused experimental targets for LHC searches, direct detection, and indirect detection experiments. **Theoretical Foundation:** The theory is built on the mathematical structure of octonions—the unique 8-dimensional normed division algebra. The non-associative property of octonions (ab)c ≠ a(bc) encodes particle identities through geometric bracket structures. The G₂ automorphism group of octonions naturally incorporates the Standard Model gauge groups (U(1) × SU(2) × SU(3)), suggesting grand unification at the Planck scale. **Contents of This Publication:** - Complete theoretical framework and mathematical foundations- Detailed mass predictions for all Standard Model particles- Quantum correction formulas and muon g-2 analysis- Dark matter identification and cosmological predictions- Comprehensive experimental test strategies- Comparison with Standard Model and beyond-Standard-Model alternatives- LaTeX source for full preprint paper- Summary documentation of 24-hour research intensive **Significance:** This represents a paradigm shift in theoretical physics: mass is determined by geometry rather than dynamical Yukawa couplings. If experimentally validated, this would be the first successful theory to predict the Standard Model mass spectrum from pure mathematics with zero free parameters, while simultaneously solving the dark matter problem. **Experimental Predictions (Testable):** - Tau g-2 = 3.91 × 10⁻⁷ (awaiting measurement)- Dark matter direct detection at recoil energies ~10-100 keV for ~200-300 GeV WIMPs- Missing energy signatures at LHC clustered near electroweak scale- Monochromatic gamma-ray line from dark matter annihilation- Multiple dark matter species with similar masses (unique signature) **Status:** Preprint ready for arXiv submission and peer review **License:** CC-BY-4.0 (Creative Commons Attribution 4.0 International) **Keywords:** octonionic algebra, mass generation, dark matter, quantum corrections, geometric unification, particle physics, beyond Standard Model, G₂ symmetry, muon g-2 anomaly, WIMP dark matter, electroweak scale **Funding:** None / Independent research --- ## Citation If you use or reference this work, please cite as: ```[Matthew Connelly] (2026).
