Abstract
A search for CP and P violation using triple-product asymmetries is performed with Λ[subscript b][superscript 0] → pK⁻π⁺π⁻, Λ[subscript b]0 → pK⁻K⁺K⁻ and Ξb0 → pK⁻K⁻π⁺ decays 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 Λ[subscript b][superscript 0] → pK−χ[subscript co](1P)(→π⁺π−, K⁺K−) decay is also reported.
