Abstract

A search for CP and P violation using triple-product asymmetries is performed with Λ0b → pKπ+π, Λ0b → pKK+K and Ξb0 → pKKπ+ decays. The data sample corresponds to integrated luminosities of 1.0 fb1 and 2.0 fb1, 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 → pKχc0(1P)(→ π+π, K+K) decay is also reported.
