"This thesis presents the measurement of the time-integrated CP asymmetries in D0->K-K+ and D0->pi-pi+ decays. The analysis uses data corresponding to an integrated luminosity of 3 fb^-1 collected at the LHCb experiment in proton-proton collision at centre-of-mass energies of 7 TeV and 8 TeV. The D0 mesons are produced in semileptonic b-hadron decays, where the charge of the accompanying muon determines the initial flavour of the D0 meson. By taking the difference of the observed asymmetries in the selected D0->K-K+ and D0->pi-pi+ samples, production and detection asymmetries cancel. The difference in CP asymmetries between the two final states is measured to be\r\nDeltaACP = AcpKK - Acppipi = (+0.14+-0.16(stat)+-0.08(syst))%. In order to obtain a measurement of AcpKK, large samples of Cabibbo-favoured D+ meson decays are used to determine production and detection asymmetries to a high precision. The CP asymmetry is found to be AcpKK = (-0.06+-0.15(stat)+-0.10(syst))%, where the correlation coefficient between DeltaACP and AcpKK is rho=0.28. By combining these results, the CP asymmetry in decays D0->pi-pi+ is derived to be Acppipi = (-0.20+-0.19(stat)+-0.10(syst))%. The results of this thesis show that there is no significant CP violation in D0->K-K+ and D0->pi-pi+ decays at the level of 10^-3."^^ . "2014" . . . . . . . "Sascha"^^ . "Stahl"^^ .
