Abstract
DESY-HERA. Measurement of the exclusive photoproduction of J/PSI mesons in the reaction GAMMA P --& gt; J/PSI P in the kinematic range of W from 20 to 290 GeV,where W is the photon-proton c.m. energy. The data come from muon decays of J/P SI collected during 1996 and 1997 with an integrated luminosity of 38 pb-1 and electron decays of J/PSI collected during 1999 and 2000 with an integrated luminosity of 55 pb-1. Both data sets come from 27.5 GeV positrons colliding with 820 GeV protons for the muon data set and 920 GeV protons for the electron data set.Allcross sections are corrected for the respective branching ratios of the J/PS I decay. Numerical values supplied by A. Bruni.
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.
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 source (direct Gemma or distilled Codex), not a consensus.
