The CP-violating asymmetries are measured to be A p K − CP = −0.020 ± 0.013 ± 0.019 and A pπ − CP = −0.035 ± 0.017 ± 0.020, and their difference A p K − CP − A pπ − CP = 0.014 ± 0.022 ± 0.010, where the first uncertainties are statistical and the second systematic. These are the most precise measurements of such asymmetries to date.10 p.application/pdfengcc-by (c) LHCb collaboration (Alfonso Albero, A. et al., 2018https://creativecommons.org/licenses/by/4.0/HadronsGran Col·lisionador d'HadronsFísica de partículesExperimentsHadronsLarge Hadron Collider (France and Switzerland)Particle physicsExperimentsinfo:eu-repo/semantics/article6845932022-06-09info:eu-repo/semantics/openAccess
