title = "Evidence for CP violation in time-integrated D0 → h-h+ decay rates",
abstract = "A search for time-integrated CP violation in D0 → h-h+ (h = K, π) decays is presented using 0.62 fb-1 of data collected by LHCb in 2011. The flavor of the charm meson is determined by the charge of the slow pion in the D∗+ → D0π+ and D∗- → D¯0π- decay chains. The difference in CP asymmetry between D0 → K-K+ and D0 → π-π+, ΔACP ≈ ACP(K-K+)-ACP(π-π+), is measured to be [-0.82 ± 0.21(stat) ± 0.11(syst)]%. This differs from the hypothesis of CP conservation by 3.5 standard deviations.",
