Abstract
Measurements of the variation of inclusive jet suppression as a function of relative azimuthal angle, $\ensuremath{\Delta}\ensuremath{\phi}$, with respect to the elliptic event plane provide insight into the path-length dependence of jet quenching. ATLAS has measured the $\ensuremath{\Delta}\ensuremath{\phi}$ dependence of jet yields in $0.14\text{ }\text{ }{\mathrm{nb}}^{\ensuremath{-}1}$ of $\sqrt{{s}_{NN}}=2.76\text{ }\text{ }\mathrm{TeV}$ $\mathrm{Pb}+\mathrm{Pb}$ collisions at the LHC for jet transverse momenta ${p}_{T}>45\text{ }\text{ }\mathrm{GeV}$ in different collision centrality bins using an underlying event subtraction procedure that accounts for elliptic flow. The variation of the jet yield with $\ensuremath{\Delta}\ensuremath{\phi}$ was characterized by the parameter, ${v}_{2}^{\mathrm{jet}}$, and the ratio of out-of-plane ($\ensuremath{\Delta}\ensuremath{\phi}\ensuremath{\sim}\ensuremath{\pi}/2$) to in-plane ($\ensuremath{\Delta}\ensuremath{\phi}\ensuremath{\sim}0$) yields. Nonzero ${v}_{2}^{\mathrm{jet}}$ values were measured in all centrality bins for ${p}_{T}<160\text{ }\text{ }\mathrm{GeV}$. The jet yields are observed to vary by as much as 20% between in-plane and out-of-plane directions.

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.
