Mass, Mixing, and the Golden Ratio: The CKM Hierarchy and Generation Mass Spectrum as Error-Correction Phenomena on the Octahedral Lattice

We derive the quark mixing hierarchy and generation mass spectrum from the error-

correction structure of the [8,4,4] code on the Q3 face-adjacency graph of the regular octa-

hedron.

We prove an exact Z2 theorem: the generation-0 bit (G0) is strictly conserved by the

single-particle walk operator on the infinite three-dimensional lattice, partitioning the three

fermion generations into sectors {1,2}(G0 = 0) and {3}(G0 = 1). This single topological

lock produces three consequences.

First, Cabibbo mixing (Vus) arises within the G0 = 0 sector through single-void virtual

excursions across the electroweak constraint boundary, while third-generation mixing (Vcb,

Vub) requires correlated two-particle tunnelling through the code’s invalid subspace, activat-

ing at the double spectral gap 2∆ = 4. In the resonance window, the ratio |Vub|/|Vcb|≈0.1

matches the experimental value 0.093 with zero fitted parameters.

Second, the generation mass hierarchy follows the Boltzmann-weighted thermodynamic

cost of propagating a frustrated codeword through the error-correcting vacuum: M=

exp(φF/2), where F is the codeword’s frustration count on Q3 and φ = (√5−1)/2 is

the reciprocal of the golden ratio. This exponent is confirmed by high-precision scanning of

the two-particle CKM resonance region in the full 65,536-dimensional virtual space.

Third, the golden ratio ϕ= (1+√5)/2 appears as the leading eigenvalue of the P4 colour

flux tube (the spectral bound governing quark confinement), while its reciprocal φ = 1/ϕ

governs the mass hierarchy. The identity κ×ϕ= φ×ϕ = 1 unifies the generation mass

spectrum with the colour confinement string tension as dual aspects of a single geometric

fixed point of the walk operator on Q3.

The framework predicts that CKM universality holds for Vus but is structurally violated

for Vcb, offering a geometric origin for the persistent∼3σ “Vcb puzzle.”
