Abstract

fetched live from OpenAlex

The kaon electroproduction reaction $^{1}\mathrm{H}$($e,{e}^{\ensuremath{'}}{K}^{+}$)$\ensuremath{\Lambda}$ was studied as a function of the virtual-photon four-momentum, ${Q}^{2}$, total energy, $W$, and momentum transfer, $t$, for different values of the virtual-photon polarization parameter. Data were taken at electron beam energies ranging from $3.40$ to $5.75$ GeV. The center of mass cross section was determined for twenty-one kinematics corresponding to ${Q}^{2}$ of $1.90$ and $2.35$ GeV${}^{2},$ and the longitudinal, ${\ensuremath{\sigma}}_{L}$, and transverse, ${\ensuremath{\sigma}}_{T}$, cross sections were separated using the Rosenbluth technique at fixed $W$ and $t$. The separated cross sections reveal a flat energy dependence at forward kaon angles not satisfactorily described by existing electroproduction models. Influence of the kaon pole on the cross sections was investigated by adopting an off-shell form factor in the Regge model, which better describes the observed energy dependence of ${\ensuremath{\sigma}}_{T}$ and ${\ensuremath{\sigma}}_{L}$.

Full frame distilled prediction

Teacher imitation

Not 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.
