A parity violating asymmetry parameter characterising the Λ0 b → J /ψΛ decay of 0.05 ± 0.17 ± 0.07 and a Λ0 b transverse production polarisation of 0.06 ± 0.07 ± 0.02 are measured, where the first uncertainty is statistical and the second systematic9 p.application/pdfengcc-by-nc-nd (c) CERN, 2013https://creativecommons.org/licenses/by-nc-nd/4.0/Física de partículesExperimentsParticle physicsExperimentsMeasurements of the Λb0→J/ψΛ decay amplitudes and the Λb0 polarisation in pp collisions at s=7 TeVinfo:eu-repo/semantics/article6290022023-03-29info:eu-repo/semantics/openAccess
