Measurement of the b-hadron production cross section using decays to D<sup>*+</sup>μ<sup>-</sup>X final states in pp collisions at âs = 7 TeV with the ATLAS detector
Bibliographic record
Abstract
The b-hadron production cross section is measured with the ATLAS detector in pp collisions at s=7TeV, using 3.3pb -1 of integrated luminosity, collected during the 2010 LHC run. The b-hadrons are selected by partially reconstructing D z.ast;+ μ - X final states. Differential cross sections are measured as functions of the transverse momentum and pseudorapidity. The measured production cross section for a b-hadron with p T > 9GeV and |n| < 2.5 is 32.7±0.8(stat.)-6.8+4.5(syst.)μb, higher than the next-to-leading-order QCD predictions but consistent within the experimental and theoretical uncertainties. © 2012.

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