| Abstract: | A search for CP violation using T-odd correlations is performed using the four-body D0 → K+K−π +π − decay, selected from semileptonic B decays. 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. |
