A search for CP violation in D^{0}→K^{-}K^{+} and D^{0}→π^{-}π^{+} decays is performed using pp collision data, corresponding to an integrated luminosity of 3 fb^{-1}, collected using the LHCb detector at center-of-mass energies of 7 and 8 TeV. The flavor of the charm meson is inferred from the charge of the pion in D^{+}→D^{0}π^{+} and D^{-}→D[over ¯]^{0}π^{-} decays. The difference between the CP asymmetries in D^{0}→K^{-}K^{+} and D^{0}→π^{-}π^{+} decays, ΔA_{CP}≡A_{CP}(K^{-}K^{+})-A_{CP}(π^{-}π^{+}), is measured to be [-0.10±0.08(stat)±0.03(syst)]%. This is the most precise measurement of a time-integrated CP asymmetry in the charm sector from a single experiment.
利用大型强子对撞机底夸克探测器（LHCb）在质心能量为7和8 TeV时收集的质子-质子（pp）碰撞数据（对应积分亮度为3 fb⁻¹），对D⁰→K⁻K⁺和D⁰→π⁻π⁺衰变中的CP破坏进行了研究。通过D⁺→D⁰π⁺和D⁻→D⁰π⁻衰变中π介子的电荷来推断粲介子的味。测量得到D⁰→K⁻K⁺和D⁰→π⁻π⁺衰变中CP不对称性的差值ΔACP≡ACP(K⁻K⁺)-ACP(π⁻π⁺)为[-0.10±0.08(统计)±0.03(系统)]%。这是单个实验对粲夸克领域时间积分CP不对称性的最精确测量。
