U.S.-Japan Cooperative Research: A Study of S=-2 Dibaryons and Hypernuclei

该奖项将支持卡内基梅隆大学物理系Peter Barnes教授和日本京都相约大学物理系Fujio Takeutchi教授之间为期两年的美日合作科学项目。这个美国小组包括来自卡内基梅隆大学和新墨西哥大学的其他调查人员，他们将前往日本开发和测试用于布鲁克海文国家实验室(BNL)实验的设备。该实验(E836)已被布鲁克海文当局批准在AGS加速器上运行。这项实验是已经完成的寻找六个夸克束缚态的实验的延续，其中两个是奇怪的夸克。美国团队将在国家高能物理实验室(KEK)进行设备性能测试，在那里可以获得同步加速器的束流时间，并将比较和检查由美国和日本小组独立执行的数据分析。它还计划在KEK开发探测器，用于一项与寻找双奇异超核有关的实验，如果H粒子不存在，则双奇异超核应该存在。这个日本小组包括京都大学和京都教育大学的研究人员，他们将前往布鲁克海文参加实验。他们将在AGS/BNL安装他们的设备并获取数据。该项目的一个目标是发展和保持凝聚力，并发展美国和日本物理学家之间未来的合作途径。

This award will support a two-year U.S.-Japan cooperative science project between Professor Peter Barnes, Physics Department, Carnegie Mellon University, and Professor Fujio Takeutchi, Department of Physics, University of Kyoto Sangyo, Kyoto, Japan. The U.S. group, which includes other investigators from Carnegie Mellon University and the University of New Mexico, will travel to Japan to develop and test equipment to be used in an experiment at Brookhaven National Laboratory (BNL). The experiment (E836) has been approved by Brookhaven authorities to operate at the AGS accelerator. The experiment is a follow-on of one already performed to search for the bound state of six quarks, two of them strange quarks. The U.S. team will work on equipment performance tests at the National Laboratory of High Energy Physics (KEK), where beam time at the synchrotron is available, and will compare and check data analysis performed independently by the U.S. and Japanese groups. It is also planned to develop detectors at KEK for an experiment related to the search for double strange hypernuclei that should exist if the H particle does not exist. The Japanese group, which includes investigators from Kyoto University and the Kyoto University of Education, will travel to Brookhaven to take part in the experiment. They will install their equipment at the AGS/BNL and take data. A goal of this project is to develop and maintain a cohesive effort and to develop future avenues of collaboration between U.S. and Japanese physicists.
