Abstract
Differential cross sections for the reaction $\ensuremath{\gamma}p\ensuremath{\rightarrow}{K}^{*0}{\ensuremath{\Sigma}}^{+}$ are presented in the photon energy range of 1.7 to 3.0 GeV. The ${K}^{*0}$ was detected by its decay products, ${K}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$, in the Continuous Electron Beam Accelerator Facility's large acceptance spectrometer (CLAS) detector at the Thomas Jefferson National Accelerator Facility. These data are the first ${K}^{*0}$ photoproduction cross sections ever published over a broad range of angles. Comparison with a theoretical model based on the vector and tensor ${K}^{*}$-quark couplings shows good agreement with the data, except at forward angles, suggesting that the role of scalar \ensuremath{\kappa} meson exchange should be investigated.
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 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; both teacher heads agree on what is shown here.
