U.S.-Netherlands Cooperative Research: Embedded Bound States in Light-Front Dynamics

9906384吉这三年奖的美国-荷兰理论核物理研究项目支持Chueng-Ryong Ji博士和一名来自北卡罗来纳州州立大学（NCSU）的研究生与荷兰阿姆斯特丹Vrije大学的Bernard Louris Gerrit Bakker博士合作。 该项目解决了量子色动力学（QCD）和相对论组分夸克模型之间的联系，可用于各种电弱形状因子计算。 该项目将确定非波函数顶点，这是在类时区域的电弱形状因子的计算中必不可少的，使用点状协变顶点，并构建描述扩展对象的非波函数模型顶点。 分析将直接应用于各种半轻子介子衰变过程。 该项目将Vrije大学小组在微扰方法上的专业知识与NCSU在光前夸克模型方法上的计划相结合。

9906384JiThis three-year award for a U.S.-Netherlands research project in theoretical nuclear physics supports Dr. Chueng-Ryong Ji and a graduate student from North Carolina State University (NCSU) for collaboration with Dr. Bernard Louris Gerrit Bakker at Vrije University in Amsterdam, The Netherlands. The project addresses the connection between the Quantum Chromodynamics (QCD) and the relativistic constituent quark model which can be used in various electroweak form factor calculations. The project will identify the non-wave-function vertices, which are essential in the calculation of electroweak form factors in the time-like region, using the pointlike covariant vertices, and construct the non-wave-function model vertices describing extended objects. The analysis will have immediate application to various semileptonic meson decay processes. The project merges the expertise of the Vrije University group on the perturbative approach with the NCSU program on the light-front quark model approach.
