The polarization is studied using the decay Λ → pπ− together with its charge conjugated process, the integrated values measured are PΛ = 0.029 ± 0.019 (stat) ± 0.012 (syst), PΛ = 0.003 ± 0.023 (stat) ± 0.014 (syst). Furthermore, the results are shown as a function of the Feynman x variable, transverse momentum, pseudorapidity and rapidity of the hyperons, and are compared with previous measurements.  2025-06-27T13:30:33Z 2025-06-27T13:30:33Z 2024 2025-06-27T13:30:34Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Reproducció del document publicat a: https://doi.org/10.1007/JHEP09(2024)082 Journal of High Energy Physics, 2024, vol. 2024, num.82 https://doi.org/10.1007/JHEP09(2024)082 cc-by (c) Aaij, R. et al., 2024 http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Springer Verlag Articles publicats en revistes (Física Quàntica i Astrofísica)
