Abstract
Conformal higher spin (CHS) field theory, which is a solid part of recent advanced checks of AdS/CFT correspondence, finds applications in cosmology. The hidden sector of weakly interacting CHS fields suggests a resolution of the hierarchy problem in the model of initial conditions for inflationary cosmology driven by a conformal field theory. These initial conditions are set by thermal garland-type cosmological instantons in the sub-Planckian energy range for the model of CHS fields with a large positive coefficient $\ensuremath{\beta}$ of the Gauss-Bonnet term in their total conformal anomaly and a large number of their polarizations $\mathbb{N}$. The upper bound of this range ${M}_{P}/\sqrt{\ensuremath{\beta}}$ is shown to be much lower than the gravitational cutoff ${M}_{P}/\sqrt{\mathbb{N}}$ which is defined by the requirement of smallness of the perturbatively nonrenormalizable graviton loop contributions. In this way we justify the approximation scheme in which the nonrenormalizable graviton sector is subject to effective field theory under this cutoff, whereas the renormalizable sector of multiple CHS fields is treated beyond perturbation theory and dynamically generates the bound on the inflation scale of the CFT cosmology ${M}_{P}/\sqrt{\ensuremath{\beta}}\ensuremath{\ll}{M}_{P}/\sqrt{\mathbb{N}}$. This confirms recent predictions for the origin of the Starobinsky ${R}^{2}$ and Higgs inflation models from the CHS cosmology, which occurs at the energy scale 3 or 4 orders of magnitude below the gravitational cutoff, $\sqrt{\mathbb{N}/\ensuremath{\beta}}\ensuremath{\sim}{10}^{\ensuremath{-}3}--{10}^{\ensuremath{-}4}$. We also consider cosmological models dominated by fermionic CHS fields with a negative $\ensuremath{\beta}$ and anomaly free models of infinite towers of CHS fields with $\ensuremath{\beta}=0$ and briefly discuss the status of unitarity in CHS models.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
