US-India Cooperative Research: Quantum Chromodynamics -A Light Front Hamiltonian Approach

0137066 VaryDescription：该奖项支持美印合作研究，题为量子染色体动力学（QCD）-一种光阵面哈密顿方法。 美国爱荷华州州立大学（ISU）的研究员詹姆斯·瓦里和印度科学家、加尔各答萨哈核物理研究所（SINP）的阿瓦洛特·哈林德拉纳特将开发一种新的方法来求解基本粒子的光谱和其他性质，该方法将物理学中的两个主要理论工具结合起来。 他们将从强相互作用的光阵面量子化理论QCD推导出控制动力学的哈密顿量，然后，他们将使用量子多体理论的新方法求解重子和介子的波函数，这些波函数表示为多夸克多胶子配置的振幅。 研究人员希望解决核物理学中几个悬而未决的问题。 范围：这项活动有可能开始执行支助股与国家方案之间的密切合作。 ISU在微观核理论和强相互作用的基本理论方面发展了实力，以及在计算物理方面的强大专业知识。 SINP在物理学基础研究方面有着很强的传统; Harindranath在光阵面量子化和量子场论中基于哈密顿的方法方面有着丰富的经验，这是这项研究的核心。 这一奖项将大大有利于美国与印度的接触，并将为一位非常有才华的印度理论家提供当之无愧的支持。 国际科学工程办公室和物理系是这项活动的共同资助者。 在印度方面，科学和技术部（DST）在NSF/DST联合计划下支持这一活动。

US investigator James Vary, Iowa State University (ISU) and Indian scientist Avaroth Harindranath, Saha Institute of Nuclear Physics (SINP), Calcutta will develop a new approach to solve for spectra and other properties of the elementary particles, which features the union of two major theoretical tools in physics. They will derive the Hamiltonian governing the dynamics from the light-front quantized theory of the strong interactions, QCD and then, they will solve for the wavefunctions of baryons and mesons expressed as amplitudes of multi-quark multi-gluon configurations using their newly developed methods of quantum many-body theory. The investigators expect to resolve several outstanding problems in nuclear physics. Scope: This activity has the potential to begin a strong collaboration between ISU and SINP. ISU has developed strength in microscopic nuclear theory and in the fundamental theory of strong interactions, as well as strong expertise in computational physics. SINP has a very strong tradition of basic research in physics; Harindranath has extensive experience in Light Front Quantization and in Hamiltonian-based methods in quantum field theory, which are central to this research. This award will greatly benefit US-Indo contacts and will provide highly deserved support to a very talented Indian theorist. The Office of International Science & Engineering and the Division of Physics are cofunders of this activity. On the Indian side, the Department of Science and Technology (DST) supports this activity under the NSF/DST joint program.
