A measurement of time-dependent CP violation in D^{0}→π^{+}π^{-}π^{0} decays using a pp collision data sample collected by the LHCb experiment in 2012 and from 2015 to 2018, corresponding to an integrated luminosity of 7.7 fb^{-1}, is presented. The initial flavor of each D^{0} candidate is determined from the charge of the pion produced in the D^{*}(2010)^{+}→D^{0}π^{+} decay. The decay D^{0}→K^{-}π^{+}π^{0} is used as a control channel to validate the measurement procedure. The gradient of the time-dependent CP asymmetry ΔY in D^{0}→π^{+}π^{-}π^{0} decays is measured to be ΔY=(-1.3±6.3±2.4)×10^{-4}, where the first uncertainty is statistical and the second is systematic, which is compatible with CP conservation.
本文展示了利用大型强子对撞机底夸克实验（LHCb）在2012年以及2015年至2018年期间收集的质子-质子碰撞数据样本（对应积分亮度为7.7 fb⁻¹）对D⁰→π⁺π⁻π⁰衰变中与时间相关的CP破坏进行的测量。每个D⁰候选粒子的初始味由D⁺(2010)⁺→D⁰π⁺衰变中产生的π介子电荷确定。D⁰→K⁻π⁺π⁰衰变用作控制通道以验证测量程序。测得D⁰→π⁺π⁻π⁰衰变中与时间相关的CP不对称性ΔY的梯度为ΔY = (-1.3±6.3±2.4)×10⁻⁴，其中第一个不确定度为统计不确定度，第二个为系统不确定度，这与CP守恒相符。
