0135659CasperThis award supports the participation of American scientists in a U.S.-Japan seminar on neutrino-nucleus interactions in the few GeV region to be held in Irvine, California from December 2-4, 2003. The co-organizers are Professor David Casper of the University of California at Irvine and Dr. Makoto Sakuda of the High Energy Accelerator Research Organization (KEK) in Tsukuba, Japan. The recent discovery of neutrino oscillation represents the first compelling evidence for physics beyond the Standard Model, and has triggered enormous interest in future experiments using intense neutrino sources. Unfortunately, the increased statistical precision afforded by more powerful beams will be of little value without corresponding progress in reducing systematic uncertainties. The very large target masses necessary to detect neutrinos are typically comprised of nuclei (Carbon, Oxygen or Iron), but data on neutrino-nucleus reactions are sparse and the effects of the nuclear target are poorly understood. Moreover, the few-GeV energy regime corresponds to the boundary between quasi-elastic and resonant pion-production processes on one hand, and deep-inelastic scattering on the other, where two qualitatively different pictures of the reaction dynamics must be reconciled. Searches for rare oscillation signals in the K2K, Mini-BOONE and MINOS experiments, as well as possible future studies aimed at probing leptonic CP violation, will rely on an accurate description of exclusive neutrino-nucleus cross-sections at these energies. As partners in these experiments the U.S. and Japan are at the forefront of the exciting and rapidly evolving field of neutrino physics. This workshop will bring together theorists and experimentalists from the particle and nuclear physics communities to lay the groundwork for future progress in understanding neutrino interactions. They will attempt to confront existing models of neutrino scattering and nuclear physics with available data and synthesize them into a coherent description, which can be applied to planned or proposed experiments. Strategies for gleaning new information from near-term experiments will be explored, as well as the prospects for collaboration on future precision measurements. The project advances international human resources through the participation of a number of graduate students. Through the exchange of ideas and technology, this project will broaden our base of basic knowledge and promote international understanding and cooperation. The researchers plan to publish proceedings of the workshop on their web sites.

0135659卡斯珀该奖项支持美国科学家参与美国- 2003年12月2日至4日在加州尔湾举行的日本几个GeV区域中微子-核相互作用研讨会。 共同组织者是加州大学欧文分校的大卫卡斯珀教授和日本筑波高能加速器研究组织（KEK）的Makoto Sakuda博士。 最近发现的中微子振荡代表了超越标准模型的物理学的第一个令人信服的证据，并引发了人们对未来使用强中微子源进行实验的极大兴趣。 不幸的是，如果在减少系统不确定性方面没有相应的进展，由更强的光束提供的增加的统计精度将没有什么价值。 探测中微子所需的非常大的目标质量通常由原子核（碳，氧或铁）组成，但中微子-原子核反应的数据很少，并且对核目标的影响知之甚少。 此外，几个GeV的能量制度对应于准弹性和共振π介子生产过程之间的边界，一方面，另一方面，深度非弹性散射，其中两个定性不同的图片的反应动力学必须调和。 在K2 K，Mini-BOONE和MINOS实验中寻找罕见的振荡信号，以及未来可能的旨在探测轻子CP破坏的研究，将依赖于对这些能量下中微子-核截面的精确描述。 作为这些实验的合作伙伴，美国和日本处于令人兴奋和快速发展的中微子物理学领域的最前沿。 这次研讨会将汇集来自粒子和核物理界的理论家和实验学家，为未来理解中微子相互作用的进展奠定基础。 他们将尝试用现有的数据来对抗中微子散射和核物理的现有模型，并将它们合成为一个连贯的描述，可以应用于计划或拟议的实验。 将探讨从近期实验中收集新信息的策略，以及未来精密测量的合作前景。 该项目通过一些研究生的参与促进国际人力资源。通过交流思想和技术，该项目将扩大我们的基础知识，促进国际理解与合作。研究人员计划在其网站上公布讲习班的会议记录。
