Search for a supersymmetric partner to the top quark in final states with jets and missing transverse momentum at √s=7 TeV with the ATLAS Detector
Bibliographic record
Abstract
A search for direct pair production of supersymmetric top squarks (t˜1) is presented, assuming the t˜1 decays into a top quark and the lightest supersymmetric particle, χ˜10, and that both top quarks decay to purely hadronic final states. A total of 16 (4) events are observed compared to a predicted standard model background of 13.5-3.6+3.7(4.4-1.3+1.7) events in two signal regions based on ∫Ldt=4.7 fb-1 of pp collision data taken at √s=7 TeV with the ATLAS detector at the LHC. An exclusion region in the t˜1 versus χ˜10 mass plane is evaluated: 370<mt˜1<465 GeV is excluded for mχ˜10∼0 GeV while mt˜1=445 GeV is excluded for mχ˜10≤50 GeV.

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; a candidate call from one teacher head, not a consensus.
