Observation of a new Ï<inf>b</inf>state in radiative transitions to Y(1S) and Y(2S) at ATLAS
Bibliographic record
Abstract
The Ï b (nP) quarkonium states are produced in proton-proton collisions at the Large Hadron Collider at âs=7TeV and recorded by the ATLAS detector. Using a data sample corresponding to an integrated luminosity of 4.4fb - 1, these states are reconstructed through their radiative decays to Î¥(1S,2S) with Î¥âμ + μ - . In addition to the mass peaks corresponding to the decay modes Ï b (1P,2P)âÎ¥(1S)γ, a new structure centered at a mass of 10.530±0.005(stat)±0.009(syst)GeV is also observed, in both the Î¥(1S)γ and Î¥(2S)γ decay modes. This structure is interpreted as the Ï b (3P) system. © 2012 CERN.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
