Abstract
We present the measurement of CP-violating asymmetries in bottom baryon decays, using Λ0b → ph−h+h− and Ξ0b → ph−h+h− decays, where h = K, π. The analysis is based on a data sample collected by the LHCb experiment in proton-proton collisions at centre-of-mass energies of 7TeV and 8TeV in 2011 and 2012, corresponding to integrated luminosities of about 1.0 fb−1 and 2.0 fb−1, respectively. The CP-violating asymmetries, based on triple products, are measured in different regions of phase space and also integrated over the phase space. We reach a sensitivity of 1% on CP-violating asymmetries, the most precise measurement in bottom baryon decays to date.
