Abstract

fetched live from OpenAlex

Under a longitudinal rescaling of coordinates ${x}^{0,3}\ensuremath{\rightarrow}\ensuremath{\lambda}{x}^{0,3}$, $\ensuremath{\lambda}\ensuremath{\ll}1$, the classical QCD action simplifies dramatically. This is the high-energy limit, as $\ensuremath{\lambda}\ensuremath{\sim}{s}^{\ensuremath{-}1/2}$, where $s$ is the center-of-mass energy squared of a hadronic collision. We find the quantum corrections to the rescaled action at one loop, in particular, finding the anomalous powers of $\ensuremath{\lambda}$ in this action, with $\ensuremath{\lambda}<1$. The method is an integration over high-momentum components of the gauge field. This is a Wilsonian renormalization procedure, and counterterms are needed to make the sharp-momentum cutoff gauge invariant. Our result for the quantum action is found, assuming $|\mathrm{ln}\ensuremath{\lambda}|\ensuremath{\ll}1$, which is essential for the validity of perturbation theory. If $\ensuremath{\lambda}$ is sufficiently small (so that $|\mathrm{ln}\ensuremath{\lambda}|\ensuremath{\gg}1$), then the perturbative renormalization group breaks down. This is due to uncontrollable fluctuations of the longitudinal chromomagnetic field.

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.
