Abstract

fetched live from OpenAlex

Charmed (and bottom) hypernuclei are studied in the quark–meson coupling (QMC) model. This completes systematic studies of charmed (Λ + c , Σ c , Ξ c ), and Λ b hypernuclei in the QMC model. Effects of the Pauli blocking due to the underlying quark structure of baryons, and the Σ c N –Λ c N channel coupling are phenomenologically taken into account at the hadronic level in the same way as those included for strange hypernuclei. Our results suggest that the Σ ++ c and Ξ + c hypernuclei are very unlikely to be formed, while the Λ + c , Ξ 0 c and Λ b hypernuclei are quite likely to be formed. For the Σ + c hypernuclei, the formation probability is non-zero, though small. A detailed analysis is also made about the phenomenologically introduced Pauli blocking and channel coupling effects for the Σ 0 c hypernuclei.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
