Measurement of the forward-backward asymmetry of electron and muon pair-production in $pp$ collisions at $\sqrt{s}$ = 7 TeV with the ATLAS detector
Bibliographic record
Abstract
The Observable is calculated as a function of the di-lepton invariant mass. The forward backward asymmetry has been calculated at detector level and then corrected with an unfolding technique. Two corrections are applied: detector resolution and QED radiative corrections (namely mass bin migration), dilution. The results are presented for the cases when only the mass bin migration correction has been applied and when both the mass bin migration and dilution corrections have been applied. A measurements of $A_{FB}$ at Dressed level is also shown. The forward-backward asymmetry has been calculated for three different final states: electron Central-Central (CC), electron Central-Forward (CF) and muons. CC electrons are required to have $p_{T}>25$ GeV and $|\eta|<2.4$, CF electrons are required to have $p_{T}>25$ GeV, one electron with $|\eta|<2.4$ and one electron with $2.5<|\eta|<4.9$. Muons are required to have $p_{T}>20$ GeV and $|\eta|<2.4$. The $A_{FB}$ has been calculated for di-lepton invariant-masses $66

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.
