Search for CP violation using triple product asymmetries in Λ 0b → pK−π+π−, Λ 0b → pK−K+K− and Ξ 0b → pK−K−π+ decays. J. High Energ. Phys. 2018, 39 (2018). https://doi.org/10.1007/JHEP08(2018)0391029-8479http://hdl.handle.net/10347/22216A 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.eng© CERN, for the bene t of the LHCb Collaboration. Article funded by SCOAP3.
