The Dalitz plot distributions for 3.1 × 106 D+ and D− candidates are compared with binned and unbinned model-independent techniques. No evidence for CP violation is found.24 p.application/pdfengcc-by (c) Camboni, Alessandro et al., 2014https://creativecommons.org/licenses/by/4.0/HadronsGran Col·lisionador d'HadronsFísica de partículesExperimentsHadronsLarge Hadron Collider (France and Switzerland)Particle physicsExperimentsinfo:eu-repo/semantics/article6457272022-05-16info:eu-repo/semantics/openAccess
