U.S. - China Cooperative Research: Theoretical Research in Medium Energy Nuclear and Particle Theory

9514190基斯林格我们建议在几个中国机构的核理论家和卡内基梅隆大学的核理论家之间开展新的合作。这些中能核子/粒子物理方面的新项目在一定程度上是建立在过去十年卓有成效的合作基础上的。主要工作之一是研究强子和原子核的夸克结构，这将为理解量子色动力学(QCD)的本质提供重要的见解，QCD是强相互作用理论。这项研究还将包括基于夸克/胶子相互作用的核子-核子和核子-超子相互作用的研究。QCD求和规则的方法将被用来帮助开发与QCD理论一致的模型。另一项工作将是研究核物质中强子性质和相互作用的修改。这项研究将包括研究重离子碰撞中的核子-核子散射，以及强子质量和耦合常数的修正。如果适用，这里也将使用QCD求和规则的方法。这项合作得到了美国-中国合作研究计划的支持。

9514190 Kisslinger We propose to initiate new collaborations between nuclear theorists at several Chinese institutions and those at Carnegie Mellon University. These new projects in medium energy nuclear/particle physics are based in part on fruitful collaborations during the past decade. One of the main efforts is the study of the quark structure of hadrons and nuclei, which will give important insight into the nature of Quantum Chromodynamics (QCD), the theory of strong interactions. This research will also include research on nucleon-nucleon and nucleon-hyperon interactions based on quark/gluon interactions. The methods of QCD sum rules will be used to help develop models consistent with QCD theory. Another effort will be the study of the modifications of hadronic properties and interactions in nuclear matter. This research will include studies of nucleon nucleon scattering in heavy ion collisions as well as the modification of hadronic masses ans coupling constants. The method of QCD sum rules will also be used here when applicable. This collaboration is supported under the U.S.-China Cooperative Research Program.
