The abstract, sentence by sentence

arXiv listing abstract v2. Results and the main claim are underlined; show every role.

The study of the longitudinal polarization of Lambda and Lambda-bar hyperons produced in polarized deep inelastic scattering, neutrino scattering, and in Z0 decays allows to access the spin dynamics of the quark fragmentation process. Different phenomenological spin transfer mechanisms are considered and predictions for the Lambda and Lambda-bar longitudinal polarization in various processes using unpolarized and polarized targets are made. Current and future semi-inclusive deep inelastic scattering experiments will provide soon accurate enough data to study these phenomena and distinguish between various models for the spin transfer mechanisms.

Hyperon-pair spin tomography beyond scalar spin correlations
hep-ph 2026-06 unverdicted novelty 7.0 of 10

Scalar Lambda-pair spin correlations leave a continuous density-matrix degeneracy; full tensor tomography is required to claim entanglement, and a ³P₀ benchmark predicts a specific anisotropy pattern.
A first look at strange-quark polarization in top-quark decays with CMS Open Data
hep-ex 2026-10 conditional novelty 6.0 of 10

A first data realization of strange-quark polarimetry in top-quark decays measures Lambda polarization in strange jets as +0.04±0.45(stat.)±0.06(syst.), consistent with both zero and LEP-based expectations.
QCD Analysis of Unpolarized and Polarized Lambda - Baryon Production in Leading and Next-to-Leading Order
hep-ph 1997-11 conditional novelty 5.0 of 10

Next-to-leading-order QCD fragmentation functions for Lambda baryons are extracted from e+e- data, and three polarized variants consistent with LEP are proposed with predictions for semi-inclusive deep-inelastic scattering.
