Resum

Abstract: A search for CP and P violation using triple-product asymmetries is performed with Λ 0 b → pK−π +π −, Λ 0 b → pK−K+K− and Ξ0 b → pK−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 Pviolating 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 0 b → pK−χc0(1P)(→ π +π −, K+K−) decay is also reported.
