The violation of CP symmetry is well established nowadays in the K and B mesons sectors. However CPV has not been observed in the baryonic sector. Charmless b-baryon decays represent a promising opportunity in this respect since their amplitudes receive contributions from tree level diagrams where the CKM element Vub appears. In addition, these decays are sensitive to possible physics beyond the SM, since they receive relevant contributions also from penguin topologies. We present the most recent measurements of charmless b-baryon decays performed by LHCb, including branching ratios and T-odd correlations.
