Abstract

A search for CP and P violation using triple-product asymmetries is performed with Λ0b → p K− π+ π−, Λ0b → p K− K+ K− and Ξ0b → p K− K− π+ decays. The data sample corresponds to integrated luminosities of 1.0 fb^−1 and 2.0 fb^−1, recorded with the LHCb detector at centre-of-mass energies of 7 TeV and 8 TeV, respectively. The CP- and P-violating asymmetries are measured both integrating over all phase space and in specific phase-space regions. No significant deviation from CP or P symmetry is found. The first observation of Λ0b → p K− χc0(1P)(→ π+ π−, K+ K−) decay is also reported.
