Measurement of the exclusive Υ production cross-section in pp collisions at s = 7 $$ \sqrt{s}=7 $$ TeV and 8 TeV
Bibliographic record
Abstract
A study is presented of central exclusive production of (nS) states, where the (nS) resonances decay to the + -final state, using pp collision data recorded by the LHCb experiment. The cross-section is measured in the rapidity range 2 < y() < 4.5 where the muons are reconstructed in the pseudorapidity range 2 < ( ) < 4.5. The data sample corresponds to an integrated luminosity of 2.9 fb -1 and was collected at centreof-mass energies of 7 TeV and 8 TeV. The measured (1S) and (2S) production crosssections are (pp p(1S)p) = 9.0 2.1 1.7 pb and

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.
