NSF-CGP Fellowship: Development of a Geant4-based Simulation of the BELLE Detector at the KEK b-Factory

该奖项支持达拉斯德克萨斯大学的Joseph Izen博士和位于日本筑波的高能物理国家实验室（KEK）的Tadao Nozaki博士的合作研究项目“在KEK b-工厂开发基于Geant4的BELLE探测器模拟”。Izen博士将在日本花一年时间研究这个项目。正在日本和美国建设的BELLE和BABAR实验将探索某些B介子衰变中的CP违反不对称性，并将测试为什么这些介子和它们的反粒子在行为上有细微差异的理论。一种新的计算机语言正在被开发并应用于高能物理实验数据的管理和解释。这个项目的目标是使用新语言实现BELLE模拟。从越来越大的数据样本中记录、重建和提取物理是一项艰巨的挑战。来自美国、日本和世界各地的粒子物理学家正在重塑他们实验的计算环境。这个合作研究项目将提供软件和设计策略方面的信息，这些信息将有利于美国和日本正在开发的高能物理实验。该项目由美国国家科学基金会和日本基金会全球伙伴关系中心的科学奖学金计划资助。＊＊＊

Izen 9722501 This award supports a collaborative research project between Dr. Joseph Izen of the University of Texas at Dallas and Dr. Tadao Nozaki of the National Laboratory for High Energy Physics (KEK) in Tsukuba, Japan on "Development of a Geant4- based Simulation of the BELLE Detector at the KEK b- Factory." Dr. Izen will spend one year working on this project in Japan. The BELLE and BABAR experiments under construction in Japan and the United States will explore CP violating asymmetries in the decays of select B mesons and will test theories of why those mesons and their antiparticles have slight differences in behavior. A new computer language is being developed and applied to the management and interpretation of data from high energy physics experiments. The goal of this project is to implement a BELLE simulation using the new language. Recording, reconstructing and extracting physics from increasingly large data samples is a formidable challenge. Particle physicists from the United States, Japan and around the world are reinventing the computing environment of their experiments. This collaborative research project will provide information on software and design strategies that will benefit high energy physics experiments now under development in both the United States and Japan. The project is supported under the Science Fellowship Program between the National Science Foundation and the Japan Foundation Center for Global Partnership. ***
