U.S.-Japan Joint Seminar: Probing Hadron Structure with Polarized Photons

9726713桑多菲该奖项支持美国科学家参加将于1999年2月22日至25日在夏威夷举行的关于用偏振光子探测强子结构的美日研讨会。联合组织者是纽约厄普顿布鲁克黑文国家实验室的安德鲁·桑多菲博士和日本大阪大学的中野隆教授。研讨会将集中研究强子结构的非微扰QCD动力学，以及如何在美国和日本的极化光子设施中用自旋可观测性有效地证明这些动力学。目标是重点发展美国和日本物理学家之间的合作，以优化两国新设施的能力，这些设施既用于未来的实验，也用于理论研究。会议将集中讨论四个主题：(L)确定重子结构中可以用Y射线束解决的最重要的问题；(2)确定美国和日本的设备，其能力与这些问题最匹配；(3)确定需要工作的关键理论领域，以便解释来自新实验的数据；以及(4)组建协作团队，全面解决这些新的具有挑战性的目标。研讨会的成果应促进对人力和设备的大笔投资的成本效益的使用。与日本专家在这一领域交换想法和数据将使美国参与者能够推进他们自己的工作，并将为未来的合作项目奠定基础。研讨会组织者特别努力让博士后研究人员参与进来。会议记录将以布鲁克海文内部报告的形式复制，并将分发给与会者以及美国和日本的相关研究小组。***

9726713 Sandorfi This award supports the participation of American scientists in a U.S.-Japan seminar on Probing Hadron Structure with Polarized Photons, to be held in Hawaii, from February 22-25, l999. The co-organizers are Dr. Andrew Sandorfi of Brookhaven National Laboratory in Upton, New York and Professor Takashi Nakano of Osaka University in Japan. The seminar will focus on a study of nonperturbative QCD dynamics of hadron structure and how these can be effectively proved with spin observables at polarized photon facilities in the U.S. and Japan. The objective is to focus on the development of collaborations between U.S. and Japanese physicists in order to optimize the capabilities of new facilities in the two countries, both for performing future experiments as well as theoretical investigations. The session will focus on four theme topics: (l) identify the most important problems in baryon structure that can be addressed with Y ray beams; (2) identify the facilities in the U.S. and Japan whose capabilities are best matched to the problems; (3) identify the key theoretical areas requiring work in order to interpret data from new experiments; and (4) form collaborative teams to fully address these new challenging goals. Results of the seminar should stimulate the cost effective use of large investments in manpower and equipment. The exchange of ideas and data with Japanese experts in this field will enable U.S. participants to advance their own work, and will set the stage for future collaborative projects. Seminar organizers have made a special effort to involve postdoctoral researchers. The proceedings of the meeting will be reproduced as a Brookhaven Internal Report and will be distributed to the participants, as well a to relevant research groups in the U.S. and Japan. ***
