标题： Update on the improved lattice calculation of direct CP-violation in K decays

摘要： 我们讨论RBC & UKQCD合作组对$\epsilon'$的格点确定状态，这是K介子衰变中直接CP破坏的度量，特别关注最近在统计技术方面的进展，用于估计大量数据的标准误差和拟合优度指标，这些数据在时间坐标和分子动力学时间上都存在相关性。 一个关键结果是提出了一种使用自助法确定拟合零分布的技术，该技术不受独立性、大$n$和/或正态数据的通常假设的限制，例如可以应用于计算即使是没有相关性的拟合的p值。 显示英文摘要

摘要： We discuss the status of the RBC & UKQCD collaboration's lattice determination of $\epsilon'$, the measure of direct CP-violation in kaon decays, focusing in particular on recent developments in statistical techniques for estimating standard errors and goodness-of-fit metrics for large amounts of data that have correlations both in the temporal coordinate and also in molecular dynamics time. A key result is the formulation of a technique for determining the null distribution of a fit using a bootstrap method that is free from the usual assumptions of independence, large-$n$ and/or normal data, that can for instance be applied to compute p-values even for uncorrelated fits.
