Quantum Spectrodynamics (QSD)

Quantum Spectrodynamics (QSD) is a theoretical framework that derives Standard Model gauge couplings from a single structural input: the [[5,1,3]] perfect quantum error-correcting code. The code determines two graphs - the complete graph K₄ (bulk exchange interactions) and the cycle graph C₅ (geometric dynamics) - from which three fundamental constants emerge: Holographic bit density: H-0.3em b₄ = 1/4 ln 2 Geometric strain: = 3/80φ² Spectral bond: = π φ² From these, with zero free parameters and a single experimental input (the Planck mass), QSD derives: Symbol Observable QSD Prediction Experimental Value Agreement α⁻¹ Fine structure constant $137.033$ $137.036$ $22$ ppm αₛ(MZ) Strong coupling at MZ $0.11781$ 0.1180 ± 0.0009 $0.16%$ sin²θW Weak mixing angle $0.23122$ 0.23122 ± 0.00003 $< 0.01%$ mH Higgs boson mass $126.7$ GeV $125.25$ GeV $1.3%$ Esyn Syndrome energy $28.24$ GeV ~ 28 GeV* $0.2%$ *CMS dimuon anomaly (CMS-PAS-HIG-20-009) The framework makes falsifiable predictions testable at the LHC.
