Very Rare Kaon Decays

斯坦福大学的一名教员、博士后助理和研究生获得了基本粒子物理学前沿领域的两个研究项目的资助。将对最近获得的数据进行分析，以得出迄今为止中性K介子罕见衰变的最佳结果。这将为标准模型理论结构的有效性提供关键测试，并为其可能的扩展和改进提供线索。中微子是基本粒子族中最轻的成员，它的质量一直是一个重要的课题。最近关于这些质量不为零的暗示为第二项活动提供了进一步的刺激，这是一项概念上的可行性研究，与国内外其他机构的物理学家合作，对不同家族的中微子的振荡进行大胆的实验研究，其目标是利用国家实验室设施进行具体的技术设计。＊＊＊

Data recently obtained will be analyzed to yield by far the best results on rare decays of neutral K mesons. That will provide critical tests of the validity of the Standard Model theoretical structure and clues to its possible extension and refinement. The masses of the neutrinos the lightest members of the elementary particle families a continuing important subject. Recent hints that those masses are not zero provide further stimulus for the second activity, a conceptual feasibility study, in collaboration with physicists at other institutions in this country and abroad, of a bold experimental search for oscillations among neutrinos in different families whose objective is a specific technical design that will make use of National Laboratory facilities. ***
