Search for a Standard Model Higgs in the H->ZZ->llvv decay channel with 4.7 fb$^{-1}$ with the ATLAS detector
Bibliographic record
Abstract
A search for a heavy Standard Model Higgs~boson decaying via htollvv, where $ell=e,mu$, is presented. It is based on proton-proton collision data at $sqrt{s}=7$~TeV, collected by the ATLAS experiment at the LHC in the first half of 2011 corresponding to an integrated luminosity of 4.7 fb$^{-1}$. The data are compared to the expected Standard Model backgrounds. Data and the combined background expectations are found to be in agreement and upper limits are placed on the Higgs boson production cross section over the entire mass window considered; in particular the production of a Standard Model Higgs boson is excluded in the region $320 < m_{mathrm{H}} < 560$~GeV at the 95% confidence level.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
