摘要

在本文中，我将介绍我们对标准模型预测的长期和短期中性K介子质量之差的计算情况。这个计算是在一个152,64 ^3 × 128$规范构型的集合上进行的，其逆晶格间距为2.36 GeV，具有物理夸克质量。我们将讨论不同分析方法的结果以及我们在获得最终结果方面的进展。

Calculation of the $K_L - K_S$ mass difference for physical quark masses

In this article, I will present the status of our calculation of the difference between the masses of the long- and short-lived neutral K mesons, $\Delta m_K$ predicted by the Standard Model. This calculation is performed on an ensemble of 152, $64^3 \times 128$ gauge configurations with an inverse lattice spacing of 2.36 GeV and physical quark masses. The results from different methods of analysis and our progress toward obtaining a final result will be discussed.
