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

9514190 Kisslinger我们建议在几家中国机构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/粒子物理领域的新项目部分是基于过去十年卓有成效的合作。其中一项主要工作是研究强子和原子核的夸克结构，这将对量子色动力学（QCD）的本质（强相互作用理论）提供重要的见解。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和规则的方法将用于帮助开发与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的改变和相互作用。这项研究将包括重离子碰撞中核子-核子散射的研究，以及强子质量和耦合常数的修正。在适用的情况下，这里也将使用QCD求和规则的方法。这项合作得到了美中合作研究项目的支持。

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.
