Abstract
Measurements of normalized differential cross-sections for top-quark pair production are presentedas a function of the top-quark transverse momentum, and of the mass, transverse momentum, and√rapidity of the t t ̄ system, in proton?proton collisions at a center-of-mass energy of s = 7 TeV . Thedataset corresponds to an integrated luminosity of 4.6 fb −1 , recorded in 2011 with the ATLAS detectorat the CERN Large Hadron Collider. Events are selected in the lepton+jets channel, requiring exactlyone lepton and at least four jets with at least one of the jets tagged as originating from a b -quark.The measured spectra are corrected for detector efficiency and resolution effects and are comparedto several Monte Carlo simulations and theory calculations. The results are in fair agreement withthe predictions in a wide kinematic range. Nevertheless, data distributions are softer than predictedfor higher values of the mass of the t t ̄ system and of the top-quark transverse momentum. Themeasurements can also discriminate among different sets of parton distribution functions.

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 it
