The studies are based on a sample of proton-proton collision data, corresponding to an integrated luminosity of 3.0fb−1, and collected by the LHCb experiment at centre-of-mass energies of 7 and 8TeV. The data are consistent with the hypothesis of no CP violation.16 p.application/pdfengcc-by (c) Alfonso Albero, Alejandro et al., 2020https://creativecommons.org/licenses/by/4.0/Simetria (Física)Teoria quàntica de campsSymmetry (Physics)Quantum field theorySearch for CP violation in Xi(+)(c) -> pK(-) pi(+) decays using model-independent techniquesinfo:eu-repo/semantics/article7064742021-07-28info:eu-repo/semantics/openAccess
