Abstract
We present a measurement of the top quark pair ( t t ¯ ) production cross section in p p ¯ collisions at s = 1.96 TeV using events with two charged leptons in the final state. This analysis utilizes an integrated luminosity of 224–243 pb −1 collected with the DØ detector at the Fermilab Tevatron Collider. We observe 13 events in the e + e − , eμ and μ + μ − channels with an expected background of 3.2 ± 0.7 events. For a top quark mass of 175 GeV, we measure a t t ¯ production cross section of σ t t ¯ = 8.6 −2.7 +3.2 ( stat ) ± 1.1 ( syst ) ± 0.6 ( lumi ) pb , consistent with the standard model prediction.
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.
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.
