Quintessence and the Higgs Portal in the Carroll limit
Bibliographic record
Abstract
A cosmological model based on two scalar fields is proposed. The first of these, $φ$, has mass $μ$, while the second, $χ$, is massless. The pair are coupled through a ``Higgs portal''. First, we show how the model reproduces the Friedmann equations if the square of the mass of the $φ$ field is proportional to the cosmological constant and $χ$ represents the quintessence field. Quantum corrections break the conformal symmetry, and the $χ$ field acquires a mass equal to $\sqrt{3gΛ}$. The perturbative approach with $g\ll 1$ is consistent with the bounds for $m_χ$; moreover, by using dimensional analysis, we estimate $m_χ\ll H_0\approx 10^{-33}$ eV, which is in accordance with what is expected in the quintessence scenario. The acceleration of the universe is proportional to $χ^2$, we conclude that for very long times, the solution of the equation of motion approaches $\langle χ\rangle \sim {m_χ}/{\sqrtλ}$ and the universe continues to accelerate, with a constant acceleration.

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.
