Measurement of the Inclusive μ Charged Current Cross Section on Carbon in the Near Detector of the T2K Experiment
Bibliographic record
Abstract
T2K has performed the first measurement of νμ inclusive charged current interactions on carbon at \nneutrino energies of ∼1 GeV where the measurement is reported as a flux-averaged double differential \ncross section in muon momentum and angle. The flux is predicted by the beam Monte Carlo and \n3 \nexternal data, including the results from the NA61/SHINE experiment. The data used for this \nmeasurement were taken in 2010 and 2011, with a total of 10.8 × 1019 protons-on-target. The \nanalysis is performed on 4485 inclusive charged current interaction candidates selected in the most \nupstream fine-grained scintillator detector of the near detector. The flux-averaged total cross section \nis hσCCi = (6.91±0.13(stat)±0.84(syst))×10−39 cm2 \nnucleon for a mean neutrino energy of 0.85 GeV.

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.
