Abstract

fetched live from OpenAlex

We consider a dark matter model offering a very natural explanation of the observed relation, ${\mathrm{\ensuremath{\Omega}}}_{\mathrm{dark}}\ensuremath{\sim}{\mathrm{\ensuremath{\Omega}}}_{\text{visible}}$. This generic consequence of the model is a result of the common origin of both types of matter (dark and visible) which are formed during the same QCD transition. The masses of both types of matter in this framework are proportional to one and the same dimensional parameter of the system, ${\mathrm{\ensuremath{\Lambda}}}_{\mathrm{QCD}}$. The focus of the present work is the detailed study of the dynamics of the $\mathcal{C}\mathcal{P}$-odd coherent axion field $a(x)$ just before the QCD transition. We argue that the baryon charge separation effect on the largest possible scales inevitably occurs as a result of merely the existence of the coherent axion field in the early Universe. It leads to preferential formation of one species of nuggets on the scales of the visible Universe where the axion field $a(x)$ is coherent. A natural outcome of this preferential evolution is that only one type of the visible baryons remains in the system after the nuggets complete their formation. This represents a specific mechanism of how the baryon charge separation mechanism (when the Universe is neutral, but the visible part of matter consists of the baryons only) replaces the conventional ``baryogenesis'' scenario.

Not 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.
