Abstract

fetched live from OpenAlex

We present a measurement of the $t\overline{t}$ differential cross section with respect to the $t\overline{t}$ invariant mass, $d\ensuremath{\sigma}/d{M}_{t\overline{t}}$, in $p\overline{p}$ collisions at $\sqrt{s}=1.96\text{ }\text{ }\mathrm{TeV}$ using an integrated luminosity of $2.7\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected by the CDF II experiment. The $t\overline{t}$ invariant mass spectrum is sensitive to a variety of exotic particles decaying into $t\overline{t}$ pairs. The result is consistent with the standard model expectation, as modeled by PYTHIA with CTEQ5L parton distribution functions.

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 imitation

Not 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.
