标题： Mixing and $CP$ violation in Charm deacys at LHCb

摘要： 本文介绍了LHCb实验中测量粲介子衰变中混合和 $CP$ 破缺的两项测量。前者是在双体 $D^0$ 衰变中测量混合可观测量 $y_{CP}-y_{CP}^{K\pi}$，后者是在 $D^+_{(s)}\rightarrow\eta^{(')}\pi^+$ 衰变中寻找直接 $CP$ 破缺。 显示英文摘要

摘要： Two measurements of mixing and $CP$ violation in charm decays performed at the LHCb experiment are presented. The former is a measurement of the mixing observable $y_{CP}-y_{CP}^{K\pi}$ in two-body $D^0$ decays, while the latter is a search for direct $CP$ violation in $D^+_{(s)}\rightarrow\eta^{(')}\pi^+$ decays.
