Abstract

fetched live from OpenAlex

A multi-channel algebraic scattering (MCAS) approach has been used to analyze the spectra of two hypernuclear systems, [Formula: see text] and [Formula: see text]. The splitting of the two odd-parity excited levels ([Formula: see text] and [Formula: see text]) at 11 MeV excitation in [Formula: see text] is driven mainly by the weak Λ-nucleus spin–orbit force, but the splittings of the [Formula: see text] and [Formula: see text] levels in both [Formula: see text] and [Formula: see text] have a different origin. These cases appear to be dominated by coupling to the collective 2 + states of the core nuclei. Using simple phenomenological potentials as input to the MCAS method, the observed splitting and level ordering in [Formula: see text] is reproduced with the addition of a weak spin–spin interaction acting between the hyperon and the spin of the excited target. With no such spin–spin interaction, the level ordering in [Formula: see text] is inverted with respect to that currently observed. In both hypernuclei, our calculations suggest that there are additional low-lying resonant states in the Λ-nucleus continua.

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.
