To cancel out production and detection charge-asymmetry effects, the search is carried out by measuring the difference between the C\!P asymmetries in a charmless decay and in a decay with an intermediate charmed baryon with the same particles in the final state. The data sample used was recorded in 2011 and 2012 with the LHCb detector and corresponds to an integrated luminosity of 3 \text { fb} ^{-1} . A total of 18 C\!P asymmetries are considered, either accounting for the full phase space of the decays or exploring specific regions of the decay kinematics. No significant C\!P-violation effect is observed in any of the measurements. cc-by (c) Badalov, Alexey et al., 2019 http://creativecommons.org/licenses/by/3.0/es info:eu-repo/semantics/openAccess Física de partícules Experiments Particle physics Experiments Measurements of CP asymmetries in charmless four-body Λb0 and Ξb0 decays info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion
