Bibliographic record
Abstract
In the Standard Model, a doublet scalar Higgs field is predicted leading to the presence of a neutral scalar particle, the Higgs boson. The LEP experiments have set a lower bound on the Higgs mass at 114.5 GeV. The electroweak precision measurements, constrain indirectly the SM Higgs boson mass to be below 144 GeV at 95 % C.L. In this mass range, the Higgs boson decay into photons is one of the most important channels for the search of this boson at LHC in ATLAS experiment. Here, we evaluate the possibility to use the associated Higgs production with a Z or W boson. The signal over background ratio is better than the inclusive analysis. The associated Higgs production can be used to increase the statistical significance of the Higgs boson discovery. It can also be used to measure the Higgs couplings to the weak bosons.

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.
