Indication of Electron Neutrino Appearance from an Accelerator-produced Off-axis Muon Neutrino Beam
Bibliographic record
Abstract
The T2K experiment observes indications of ! e appearance in data accumulated with \n1:43 1020 protons on target. Six events pass all selection criteria at the far detector. In a three- \n \navor neutrino oscillation scenario with j m2 \n23j = 2:4 103 eV2, sin2 2 23 = 1 and sin2 2 13 = 0, \nthe expected number of such events is 1.5 0.3(syst.). Under this hypothesis, the probability to \nobserve six or more candidate events is 7 103, equivalent to 2.5 signi cance. At 90% C.L., \nthe data are consistent with 0.03(0.04)< sin2 2 13 < 0.28(0.34) for CP = 0 and normal (inverted) \nhierarchy.

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.
