Abstract
The search for the Higgs boson in the WW channel is presented using data samples collected in 2011 and 2012 with the ATLAS detector [1] at the LHC.The data collected corresponds to 4.6 fb -1 and 20.7 fb -1 collected at a center-of-mass energy of 7 TeV and 8 TeV, respectively.The search focuses on a Higgs boson predicted by the Standard Model and produced by gluon-gluon fusion and vector boson fusion.At a Higgs mass of = 125 GeV, an excess over the expected number of background events is expected to be 3.7 standard deviations, while the observed is 3.8.The ratio of the observed number of events to the expected is = 1.01 ± 0.31 for the combined searches in the channel for 0, 1 and ≥ 2 jet multiplicities.A coupling measurement performed is shown to be consistent with the value predicted by the Standard Model.Finally a spin analysis is described which supports evidence for a Higgs particle of spin 0 + .

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
