INT 9515511 Vary This U.S.-Slovak theoretical physics project between Dr. James Vary of the Iowa State University and Dr. Lubomir Martinovic of the Slovak Academy of Sciences' Institute of Physics will examine light-front quantization. The goal of the team is to use a systematic and practical approach to the evaluation of the Hamiltonian framework in quantum field theory for analytical and numerical applications. The researchers intend to focus their efforts on quantum chromodynamics (QCD), a strongly interacting field theory that can be compared with experiments in the non-perturbative regime. Test applications will be developed to demonstrate concepts and illustrate utility. Initial efforts will feature a 1+1 dimension problem and a second one, in 3+1 dimension, that will incorporate findings from the first. This work should yield models for investigating specific formal and numerical issues in field theories. Overall, results are expected to facilitate the construction of equations for effective Hamiltonian methods useful in study of high energy physics phenomenology. This project combining nuclear theory and mathematical physics fulfills the program objective of advancing scientific knowledge by enabling experts in the Untied States and Eastern Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence. ??

这个由爱荷华州立大学的James Vary博士和斯洛伐克科学院物理研究所的Lubomir Martinovic博士合作的美国-斯洛伐克理论物理项目将研究光前量子化。该团队的目标是使用系统和实用的方法来评估量子场论中的哈密顿框架，以用于分析和数值应用。研究人员打算把他们的努力集中在量子色动力学（QCD）上，这是一种强相互作用的场理论，可以与非摄动状态下的实验进行比较。将开发测试应用程序来演示概念和说明实用性。最初的努力将以1+1维度的问题为特色，第二个问题将以3+1维度的问题为特色，其中将包含第一个问题的发现。这项工作将为研究场论中具体的形式和数值问题提供模型。总的来说，这些结果有望促进对高能物理现象学研究有用的有效哈密顿方法的方程的构建。该项目将核理论与数学物理相结合，通过使美国和东欧的专家在共同感兴趣和能力强的领域结合互补的人才和共享研究资源，实现了推进科学知识的计划目标。?？
