The measured CP-violating charge asymmetries are ACP (D± →η‧π±) = (- 0.61 ± 0.72 ± 0.53 ± 0.12)% and ACP (Ds± →η‧π±) = (- 0.82 ± 0.36 ± 0.22 ± 0.27)%, where the first uncertainties are statistical, the second systematic, and the third are the uncertainties on the ACP (D± →KS0 π±) and ACP (Ds± → ϕπ±) measurements used for calibration. The results represent the most precise measurements of these asymmetries to date.10 p.application/pdfengcc-by (c) Camboni, Alessandro et al., 2017https://creativecommons.org/licenses/by/4.0/HadronsGran Col·lisionador d'HadronsFísica de partículesExperimentsHadronsLarge Hadron Collider (France and Switzerland)Particle physicsExperimentsinfo:eu-repo/semantics/article6780112022-06-08info:eu-repo/semantics/openAccess
