Abstract

fetched live from OpenAlex

A new spectrometer system has been designed and constructed at the secondary beam line K1.8BR in the hadron hall of J-PARC to investigate K N interactions and K -nuclear bound systems. The spectrometer consists of a high precision beam line spectrometer, a liquid 3 He/ 4 He/D 2 target system, a cylindrical detector system that surrounds the target to detect the decay particles from the target region, and a neutron time-of-flight counter array located 15 m downstream of the target position. Details of the design, construction, and performance of the detector components are described. . . . .

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.
