(on behalf of the BABAR Collaboration) We report on a measurement of D0 − D0 mixing and a search for CP violation in the D0 → K+K−, pi+pi − and K±pi ∓ channels. We use D0’s coming from D∗+ decays, so that the flavour of the D0 at produc-tion is tagged by the charge of the pion that is also emitted. We also use an independent set of D0’s coming directly from the hadronization of the charm quark, but in this case the flavour of the charmed meson is not known. We analyze events collected by the BABAR experiment at the PEP-II asymmetric-energy e+e − collider, corresponding to an inte-grated luminosity of 468 fb−1. We measure the mixing parameter value to be yCP = [0.72 ± 0.18(stat) ± 0.12(syst)]%, and exclude the no-mixing hypothesis at 3.3σ significance. We find no evidence of CP violation, ob-serving ∆Y = [0.09 ± 0.26(stat) ± 0.06(syst)] % which is consistent with zero
