项目摘要
0003701BassalleckThis award supports a three-year collaborative research project between Professor Bernd Bassalleck of the University of New Mexico and Professor Tomokazu Fukuda of the High Energy Accelerator Research Organization (KEK) in Japan. The researchers will undertake a study of hyperon-hyperon and hyperon-nucleon interaction. This is the most fundamental baryon-baryon interaction involving one and two strange quarks, respectively. The primary focus of the proposal is the approved KEK experiment E452. Its goal is the study of the spin-dependent interaction between the E+ hyperon and the proton, in particular the E+ spin-orbit interaction, which is predicted to be large. What makes this particularly interesting is the sharp contrast to the now firmly established smallness of the A spin-orbit interaction. The actual measurement to be performed is the left-right asymmetry in the elastic scattering of polarized E+ off protons using a novel scintillation detector with Image Intensifier and CCD readout for complete 3-dimensional track reconstruction. The project brings together the efforts of two laboratories that have complementary expertise and research capabilities. Results of this research should provide a significant enhancement of our understanding of the fundamental baryon-baryon interaction utilizing the strange quark as a special probe not normally available in conventional nuclear physics. 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 results of their research in scientific journals and report on the findings at scientific meetings.
该奖项支持新墨西哥大学Bernd Bassalleck教授和日本高能加速器研究组织(KEK)的Tomokazu Fukuda教授之间为期三年的合作研究项目。研究人员将进行超子-超子和超子-核子相互作用的研究。这是最基本的重子-重子相互作用,分别涉及一个和两个奇异夸克。该提案的主要焦点是已批准的KEK实验E452。它的目标是研究E+超子和质子之间的自旋依赖相互作用,特别是E+自旋轨道相互作用,预计这是很大的。特别有趣的是,这与现在已经确定的A自旋轨道相互作用较小形成了鲜明的对比。实际测量的是极化E+ off质子弹性散射的左右不对称性,使用一种带有图像增强器和CCD读数的新型闪烁探测器来完成三维轨迹重建。该项目汇集了两个具有互补专业知识和研究能力的实验室的努力。这项研究的结果将大大增强我们对重子-重子相互作用的基本理解,利用奇异夸克作为传统核物理学中通常无法获得的特殊探针。通过思想和技术的交流,该项目将扩大我们的基础知识基础,促进国际了解与合作。研究人员计划在科学期刊上发表他们的研究结果,并在科学会议上报告他们的发现。
