Abstract

fetched live from OpenAlex

We report on our study of the inclusive electron scattering off 4 He, where emphasis on the role of three-nucleon forces is given. A detailed analysis of the longitudinal response function R L (ω, q) is done at different kinematics and theoretical results are compared to available experimental data. Calculation are performed with ab-initio techniques where the full four-body continuum dynamics is considered via the Lorentz integral transform method. At lower momentum transfer ( q ≤ 200 MeV/c) three-nucleon forces play an important role and the two three-nucleon force models implemented show differences up to 10%.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
