Abstract

fetched live from OpenAlex

Two-particle azimuthal correlation functions are presented for charged hadrons produced in $\mathrm{A}\mathrm{u}+\mathrm{A}\mathrm{u}$ collisions at the Relativistic Heavy Ion Collider ($\sqrt{{s}_{NN}}=130\text{ }\text{ }\mathrm{G}\mathrm{e}\mathrm{V}$). The measurements permit determination of elliptic flow without event-by-event estimation of the reaction plane. The extracted elliptic flow values (${v}_{2}$) show significant sensitivity to both the collision centrality and the transverse momenta of emitted hadrons, suggesting rapid thermalization and relatively strong velocity fields. When scaled by the eccentricity of the collision zone $\ensuremath{\epsilon}$, the scaled elliptic flow shows little or no dependence on centrality for charged hadrons with relatively low ${p}_{T}$. A breakdown of this $\ensuremath{\epsilon}$ scaling is observed for charged hadrons with ${p}_{T}\text{ }&gt;1.0\text{ }\text{ }\mathrm{G}\mathrm{e}\mathrm{V}/c$.

Full frame distilled prediction

Teacher imitation

Not 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.
