The data sample corresponds to integrated luminosities of 1.0 fb−1 and 2.0 fb−1 recorded at the centreof-mass energies of 7 TeV and 8 TeV, respectively. The CP-violating asymmetry a T-odd CP is measured to be (0.18±0.29 (stat)±0.04 (syst))%. Searches for CP violation in different regions of phase space of the four-body decay, and as a function of the D0 decay time, are also presented. No significant deviation from the CP conservation hypothesis is found.23 p.application/pdfengcc-by (c) Comerma-Montells, A. 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/article6457422022-05-16info:eu-repo/semantics/openAccess
