U.S.-Egypt Cooperative Research: Time Asymmetry and Relativistic Resonances

该奖项旨在支持德克萨斯大学奥斯汀分校物理系的Arno Bohm博士和埃及赫尔万大学数学系的Soliman Komy博士和Hani Kaldass博士之间的合作研究。PI将研究原子、原子核和相对论粒子物理中的共振和衰变现象的统一描述。这门学科已经从单纯的数学努力发展到解决量子物理中的一个重要问题：共振、散射和衰变现象的统一理论。这样的理论将克服粒子数据组面临的相对论共振的质量和宽度定义的模糊性，例如对于Weinberg Z玻色子或费米介子-核子共振。共振理论，以及与之相关的一种新的量子力学时间不对称性，已经成为一个国际物理学家团体--国际量子理论小组(www.ph.utexas.edu/bohmwww/index.html)的项目。将对开罗的一个计算机系统进行升级，以满足科学文件和数据交流的需要。其中一个埃及团队H.Kaldass在DESY制造计算机时获得的专业知识，将帮助与IQT Group的成员合作开发，IQT Group是一个运行Linux的个人电脑系统。这将使这个团队保持更密切的联系，并与IQT小组的其他专家保持联系。它还将让新一代学生和青年科学家在更紧密的接触中成长。科米博士是一名数学物理学家，他将更关心受操纵的希尔伯特空间(也称为Gelfand Triplet)的数学问题。他将使一般数学理论适应哈代函数的具体需要，也将协调初级科学家和研究生和本科生的研究。从物理学家的角度来看，卡尔达斯博士是这一领域的专家，他将致力于物理相关问题的表述，并将理论结果与实验数据进行比较。特别是，他将把这一理论应用于共振生产。博姆博士将与德克萨斯州和德国的原子物理学家一起研究半群时间零(时间开始)的解释问题。他还将致力于相对论共振理论的研究。他还将与国际理论小组成员协调埃及研究人员的工作。范围和更广泛的影响国际量子理论小组每年举办研讨会并出版会议记录。A·博姆和S·科米都在里斯本会议上发表了演讲，里斯本会议是国际数学物理大会的卫星。私人投资机构的目标是加入这些国际努力，并在开罗举办未来关于时间不对称量子理论和共振的研讨会之一。通过计算机联系，加上相互访问，将提高科学生产力，并将导致技术转让和不同国家年轻一代之间更好的相互了解。该项目得到了美国-埃及联合基金计划的支持，该计划为两国的科学家和工程师提供资助，以开展这些合作活动。

0421936BohmDescription: This award is to support a cooperative research between Dr. Arno Bohm, Physics Department, University of Texas, Austin, Texas and an Egyptian team including Drs. Soliman Komy and Hani Kaldass, Department of Mathematics, Helwan University, Helwan, Egypt. The PIs will study a unified description of resonance and decay phenomena in atomic, nuclear and relativistic particle physics. The subject has developed from a merely mathematical endeavor to the solution of an important problem in quantum physics: a unified theory of resonance scattering and decay phenomena. Such a theory will overcome the ambiguity in the definition of mass and width for relativistic resonances faced by the particle data group, e.g., for the Weinberg Z-boson or the Fermi pion-nucleon resonance. The theory of resonances, and connected with it a new quantum mechanical time asymmetry has become the project of an international group of physicists, The International Quantum Theory Group (www.ph.utexas.edu/bohmwww/index.html). A computer system in Cairo will be upgraded to fulfill the needs for communication of scientific documents and data. The expertise that one of the Egyptian team, H. Kaldass, had acquired while building computers at DESY, will help develop in collaboration with members of IQT Group, a system of PC's running linux. This will allow this team to stay in closer contact with each other and with other experts in the IQT Group. It will also allow the new generation of students and young scientists to grow up in closer contact with each other. Dr. Komy who is a mathematical physicist will be more concerned with the mathematical questions of the Rigged Hilbert Spaces (also called Gelfand Triplets). He will adapt the general mathematical theory to the specific needs for Hardy functions, and will also coordinate the research of the junior scientists and the graduate and under-graduate students. Dr. Kaldass is a specialist in this field from the physicist point of view, and will work on the formulation of the physically relevant questions and compare the theoretical results with the experimental data. In particular he will apply this theory to resonance production. Dr. Bohm will work on the question of the interpretation of the semigroup time zero (beginning of time) with atomic physicists at Texas and in Germany. He will also work on the theory of relativistic resonance. He will also coordinate the work of the Egyptian researcher with the members of the International Theory Group. Scope and broader impacts The International Quantum Theory Group holds annual workshops and publishes proceedings. Both A. Bohm and S. Komy delivered lectures at the Lisbon meeting, which was a satellite of the international Congress on Mathematical Physics. The PIs aim to join these international efforts and hold one of the future workshops on time asymmetric quantum theory and resonances in Cairo. The contacts via computers, together with the reciprocal visits will enhance the scientific productivity, and will lead to transfer of technology and to a better mutual understanding between the young generations of the different countries. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
