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

该奖项支持美印合作研究，名为量子色动力学(QCD) -光前哈密顿方法。爱荷华州立大学（ISU）的美国研究员James Vary和印度加尔各答萨哈核物理研究所（SINP）的科学家Avaroth Harindranath将开发一种新的方法来求解基本粒子的光谱和其他特性，该方法以物理学中两种主要理论工具的结合为特色。他们将从强相互作用的光前量子化理论（QCD）中推导出控制动力学的哈密顿量，然后，他们将利用他们新开发的量子多体理论方法求解以多夸克多胶子构型振幅表示的重子和介子的波函数。研究人员希望解决核物理学中的几个突出问题。范围：这项活动有可能开始ISU和SINP之间强有力的合作。ISU在微观核理论和强相互作用的基础理论方面发展了实力，在计算物理方面也有很强的专业知识。SINP在物理学基础研究方面有很强的传统；Harindranath在光前量子化和基于哈密顿的量子场论方法方面有着丰富的经验，这是本研究的核心。这个奖项将极大地促进美印关系，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。国际科学与工程办公室和物理系是这项活动的共同发起者。在印度方面，科学技术部支持在国家科学基金会/科学技术部联合项目下的这一活动。

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.
