标题： Status of B_K from Lattice QCD

摘要： 给出了与理解中性 K介子 sector 中的间接 CP 破坏相关的袋参数 B_K 的格点计算的简要回顾。还介绍了目前最先进的计算状态报告，并讨论了传递给现象学家的 B_K 值。这是 2002 年 2 月 13 日至 16 日在 CERN 举行的 CKM 单位arity 三角形 Workshop 上发表的回顾的浓缩和更新版本 (http://ckm-workshop.web.cern.ch/ckm-workshop/)。 显示英文摘要

摘要： A brief review of lattice calculations of the bag parameter B_K relevant for understanding indirect CP violation in the neutral kaon sector is given. A status report on current state-of-the-art calculations is presented as well as a discussion of the value of B_K exported to phenomenologists. This is a condensed and updated version of the review presented at the CKM Unitarity Triangle Workshop held at CERN during Feburary 13-16, 2002 (http://ckm-workshop.web.cern.ch/ckm-workshop/).
