Abstract

A search for time-integrated CP violation in D-0 -> h(-)h(+) (h = K, pi) 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*(+) -> D-0 pi(+) and D*(-) -> (D) over bar (0)pi(-) decay chains. The difference in CP asymmetry between D-0 -> K-K+ and D-0 -> pi(-)pi(+), Delta A(CP) A(CP)(K-K+) - A(CP)(pi(-)pi(+)), 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.
