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