Abstract

A search for CP and P violation using triple-product asymmetries is performed with Λb 0 → pKπ+π, Λb 0 → pKK+K and Ξb 0 → pKKπ+ 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 Λb 0 → pKχc0(1P)(→π+π, K+K) decay is also reported.
