Measurement of the inclusive isolated prompt photon cross section inppcollisions ats=7 TeVwith the ATLAS detector
Bibliographic record
Abstract
A measurement of the cross section for the inclusive production of isolated prompt photons in $pp$ collisions at a center-of-mass energy $\sqrt{s}=7\text{ }\text{ }\mathrm{TeV}$ is presented. The measurement covers the pseudorapidity ranges $|{\ensuremath{\eta}}^{\ensuremath{\gamma}}|<1.37$ and $1.52\ensuremath{\le}|{\ensuremath{\eta}}^{\ensuremath{\gamma}}|<1.81$ in the transverse energy range $15\ensuremath{\le}{E}_{\mathrm{T}}^{\ensuremath{\gamma}}<100\text{ }\text{ }\mathrm{GeV}$. The results are based on an integrated luminosity of $880\text{ }\text{ }{\mathrm{nb}}^{\ensuremath{-}1}$, collected with the ATLAS detector at the Large Hadron Collider. Photon candidates are identified by combining information from the calorimeters and from the inner tracker. Residual background in the selected sample is estimated from data based on the observed distribution of the transverse isolation energy in a narrow cone around the photon candidate. The results are compared to predictions from next-to-leading-order perturbative QCD calculations.

How this classification was reachedexpand
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.
