A comprehensive study of the angular distributions in the bottom-baryon decays , followed by with or decays, is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. The decay parameters and the associated charge-parity ( ) asymmetries are measured, with no significant violation observed. For the first time, the decay parameters are measured. The most precise measurements of the decay parameters , , and are obtained for decays and an independent measurement of the decay parameters for the strange-baryon decay is provided. The results deepen our understanding of weak decay dynamics in baryon decays. © 2024 CERN, for the LHCb Collaboration2024CERN
