Abstract
A search for events containing an isolated electron or muon and missing transverse momentum produced in e ± p collisions is performed with the H1 and ZEUS detectors at HERA.The data were taken in the period 1994-2007 and correspond to an integrated luminosity of 0.98 fb -1 .The observed event yields are in good overall agreement with the Standard Model prediction, which is dominated by single W production.In the e + p data, at large hadronic transverse momentum P X T > 25 GeV, a total of 23 events are observed compared to a prediction of 14.0 ± 1.9.The total single W boson production cross section is measured as 1.06 ± 0.16 (stat.)± 0.07 (sys.)pb, in agreement with an Standard Model (SM) expectation of 1.26 ± 0.19 pb.
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
