Abstract
© 2012, CERN for the benefit of the ATLAS collaboration. In this paper, a measurement of Ï polarization in W â Ïν decays is presented. It is measured from the energies of the decay products in hadronic Ï decays with a single final state charged particle. The data, corresponding to an integrated luminosity of 24 pb < sup > â1 < /sup > , were collected by the ATLAS experiment at the Large Hadron Collider in 2010. The measured value of the Ï polarization is P < inf > Ï < /inf > = â1.06±0.04 (stat) < sup > +0.05 < /sup > < inf > â0.07 < /inf > (syst), in agreement with the Standard Model prediction, and is consistent with a physically allowed 95 % CL interval [â1,â0.91]. Measurements of Ï polarization have not previously been made at hadron colliders.

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
