Results are given in terms of ft and interference fractions between the diferent components contributing to this fnal state. Only Λ resonances decaying to pK− are found to be relevant, where the largest contributions stem from the Λ(1520), Λ(1600), Λ(1800), and Λ(1890) states.37 p.application/pdfengcc-by (c) Aaij, R. et al., 2024http://creativecommons.org/licenses/by/4.0/HadronsFísica de partículesCromodinàmica quànticaHadronsParticle physicsQuantum chromodynamicsinfo:eu-repo/semantics/article7564752025-07-04info:eu-repo/semantics/openAccess
