Abstract
To search for an <f>${\\rm S} = -1$</f> di-baryonic state which decays to <f>$\\Lambda p$</f>, the <f>${}^3{\\rm He}(K^-,\\Lambda p)n_{\\rm missing}$</f> reaction was studied at 1.0 <f>${\\rm GeV}/c$</f>. Unobserved neutrons were kinematically identified from the missing mass <f>$M_{X}$</f> of the <f>${}^3{\\rm He}(K^-,\\Lambda p)X$</f> reaction in order to have a large acceptance for the <f>$\\Lambda pn$</f> final state. The observed <f>$\\Lambda pn$</f> events, distributed widely over the kinematically allowed region of the Dalitz plot, establish that the major component comes from a three-nucleon absorption process. A concentration of events at a specific neutron kinetic energy was observed in a region of low momentum transfer to the <f>$\\Lambda p$</f>. To account for the observed peak structure, the simplest S-wave pole was assumed to exist in the reaction channel, having a Breit–Wigner form in energy and with a Gaussian form factor. A minimum <f>$\\chi ^2$</f> method was applied to deduce its mass, <f>$M_X = 2355^{+6}_{-8}$</f> (stat.) <f>$\\pm $</f>12 (syst.) <f>${\\rm MeV}/c^2$</f>, and decay width, <f>$\\Gamma _X = 110^{+19}_{-17}$</f> (stat.) <f>$\\pm $</f>27 (syst.) <f>${\\rm MeV}/c^2$</f>, respectively. The form factor parameter <f>$Q_X \\sim $</f> 400 <f>${\\rm MeV}/c$</f> implies that the range of the interaction is about 0.5 fm.

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 it
