New Physics Predictions

What GTE forbids (SUSY, axion, dark photon, extra dimensions) and what it predicts (mirror dark sector, GTE-P7 at 211.9 MeV, proton topological stability, ΛGTE = 2.03 GeV). Every item is derived, not assumed.

Why the LHC Has Found Nothing Beyond the Higgs

Since the Higgs boson was confirmed in 2012, the Large Hadron Collider has found no evidence of physics beyond the Standard Model — no supersymmetric particles, no extra dimensions, no new forces. Many BSM theories predicted particles that should already have appeared at TeV energies. They have not.

This is a confirmed GTE prediction. GTE derives the complete particle spectrum from the Z₇ winding sectors of ΦMDL: exactly five SM winding sectors (w ∈ {0,2,3,4,6}) plus the dark-mirror branch (w ∈ {1,5}). No additional sectors are available. Supersymmetric partners would require a doubling of the winding spectrum — for which the certificate structure has no mechanism. Every null LHC result is consistent with this derivation.

What GTE Forbids: Structural Absences

The following are not merely unpredicted — they are structurally impossible within the GTE certificate structure. Every null experimental result is a confirmed GTE prediction.

No Supersymmetry
SM particle ontology is exhausted by the Z₇ winding sectors {0,2,3,4,6}. No mechanism generates a winding-sector doubling for superpartners.
LHC null results up to ~2 TeV: confirmed prediction
No Axion
The strong CP angle θQCD = 0 exactly from F₂₁ group theory (three independent CatAL proofs). No axion mechanism is needed or predicted.
Every null ADMX/CASPEr/BabyIAXO result: confirmed prediction
No Dark Photon
The Elegant Kernel for the mirror winding sector has no U(1) factor — Lean-certified. The dark sector has SU(3)dark only; no vector portal coupling exists.
Every null NA64/BaBar/Belle II/NA62 result: confirmed prediction
No Large Extra Dimensions
The 3+1D spacetime structure is derived: the CMCA has one non-trivial persistent-glider sector living in 1+1D; the Algebraic Lifting Theorem (CatAL) lifts this to 3+1D. No compact extra dimensions are available.
LHC Kaluza-Klein null searches: confirmed prediction

What GTE Predicts: The Mirror Dark Sector

The Z₇ arithmetic that generates the SM winding sectors {0,2,3,4,6} does not exhaust Z₇. The complementary sectors {1,5} are equally consistent with Z₇ arithmetic — they form the mirror branch, a dark sector forced by the same arithmetic as the SM itself.

Mirror particles carry SU(3)dark color and no SM gauge charges: no electric charge, no SM weak charge, no SM color. The winding algebra forbids SM-gauge coupling at dimension-4. They are dark by construction.

Primary dark matter candidate (UFIDM)
24.5 MeV
χ₂ — Generation 2
Dark lepton (MeV-scale astrophysics)
3.60 GeV
χ₃ — Generation 3

These masses are CatAD: derived from the same cascade formula that gives SM lepton masses at 0.295% RMS precision, applied to mirror-branch winding inputs. The mass ratios are predicted: mχ₂/mχ₁ = 45.4. If any one mass is confirmed, the theory predicts where to find the other two.

Dark matter candidate χ₁ at 0.54 MeV: Relic density ΩDMh² = 0.11994 (CatAD, matches Planck 2018 to −0.15%). Spin-independent cross-section with SM nucleons σSI ~ 10−61 cm² — about 30 orders of magnitude below any current or projected direct-detection threshold. This dark matter is invisible to WIMP-style searches. Every null WIMP result is consistent with this prediction.

GTE-P7: The Highest-Priority New Physics Signal

CatAD

Dark lepton resonance at 211.9 MeV

GTE-P7 is a resonance appearing in the Elegant Kernel computation for the mirror branch — derived from the same UCL pipeline that generates SM lepton masses, applied to a specific mirror-branch cascade triple. Its mass arises from the mirror-branch winding sector with zero free parameters.

The 211.9 MeV mass lies in the range accessible to Belle II, currently taking data. Observable channels: e⁺e⁻ → χ + invisible (single charged track + missing energy), and displaced-vertex signatures with centimeter-scale decay length.

Belle II — full 50 ab⁻¹ dataset by 2031 | Search window: [200, 225] MeV
Falsification: The GTE-P7 prediction is falsified if no resonance is observed in the 200–225 MeV window after the full 50 ab−1 dataset, at the expected coupling scale. This is one of the highest-priority experimental targets in the GTE programme.

Other Key Predictions

CatAL

Proton topological stability (dimension-4)

Baryon number is a topological charge of the Z₇ winding field: B = (1/3)Σj χq(wj). Topological charges cannot change under any local field operator of dimension ≤ 4. Dimension-4 proton decay is structurally impossible — not merely suppressed.

Important: Dimension-6 operators (GUT-scale suppressed, ~MGUT⁻²) are not forbidden. The standard GUT channel p → e⁺π⁰ may exist at dimension-6.

The ΛGTE = 2.03 GeV scale

The kink dissolution threshold ΛGTE = 7 × Mkink = (8/7)mτ ≈ 2.03 GeV is where individual kinks dissolve into the ΦMDL substrate. This is derived, not tunable — it is fixed by mτ and |Z₇| = 7, both of which are themselves derived.

Observable signatures near √s ≈ 2 GeV: a change in the effective number of hadronic degrees of freedom, anomalous energy deposition patterns, and a transition in the kink structure function observable in lattice QCD calculations.

Gravitational wave background from Z₇ phase transition

The Z₇ domain-wall annihilation at TG ≈ 0.70 GeV produces a stochastic gravitational wave background peaked in the frequency band of the Einstein Telescope and LISA. The signal is generated by the collapse of the Kibble foam within ~10−24 s of formation.

Neutrino mass sum Σmν = 59.4 meV

The total neutrino mass sum (Normal Ordering) is derived from the GTE neutrino cascade, giving Σmν = 59.4 meV. Current cosmological constraint: Σmν < 120 meV (Planck 2018). The GTE prediction is comfortably inside the current bound and will be testable by CMB-S4 and Euclid at the ~10 meV level.
