AB  - A comprehensive study of the angular distributions in the bottom-baryon decays Lambda(0)(b) ->Lambda(+)(c)h(-) (h = pi,K) , followed by Lambda(0)(c) ->Lambda h(+) with Lambda -> p pi(-) or Lambda(+)(c)-> pK(S)(0) decays, is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 9 fb(-1) collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. The decay parameters and the associated charge-parity (CP) asymmetries are measured, with no significant CP violation observed. For the first time, Lambda(0)(b) ->Lambda(+)(c)h(-) decay parameters are measured. The most precise measurements of the decay parameters alpha, ss, and are obtained for Lambda(+)(c) decays and an independent measurement of the decay parameters for the strange-baryon Lambda decay is provided. The results deepen our understanding of weak decay dynamics in baryon
