Quenching jets increases their flavor
Bibliographic record
Abstract
The widespread notion that jets quenched in a quark-gluon-plasma (QGP) are similar in their parton flavor composition to jets in vacuum is critically examined. We demonstrate that while the soft to semihard (low to intermediate transverse momentum ${p}_{T}$) sector of vacuum jets are predominantly bosonic i.e., composed of gluons, sufficiently quenched jets can have an intermediate momentum sector that is predominantly fermionic, dominated by quarks and antiquarks. We demonstrate, using leading-order perturbative QCD processes, that the rate of flavor conversion from a gluon traversing the QGP as part of a jet, to a quark or antiquark, versus the reverse process, grows steadily with falling ${p}_{T}$. Simple diagrammatic estimates are followed by a variety of realistic simulations in static media, which demonstrate qualitatively similar yet quantitatively different fermion enhancements. The relation of this increase in flavor to the observed baryon enhancement at intermediate ${p}_{T}$ is studied in a fully realistic simulation.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
