Theoretical Nuclear Physics

现在人们认为强核力的正确理论是量子色动力学（称为QCD），夸克与胶子相互作用形成强子的理论，强子是核物理学中观察到的粒子。 我们的研究目标是研究强子和原子核的结构，以探讨QCD和电弱理论。 热的早期宇宙被认为是由夸克蒸汽组成的，它经历了一个相变，形成夸克凝聚和强子。 我们正在研究强子性质所揭示的这些凝聚物的结构，并将在杰斐逊实验室和其他中能加速器上进行测试。 我们对弱核力的研究探讨了类似于铁磁体磁化率的夸克凝聚体。 在与中国理论家的合作中，我们研究了胶球，无夸克强子，将在美国的加速器上进行测试，中国和欧洲。我们正在研究高温下的强子，希望在RHIC加速器上能观察到早期宇宙相变的一些特征。 作为这项研究的一部分，我们开发的模型，可用于分析中能实验。

It is now believed that the correct theory of the strong nuclear force is Quantum Chromodynamics (called QCD), the theory of quarks interacting with gluons to form hadrons, the observed particles of nuclear physics. The goals of our research are to study the structure of hadrons and atomic nuclei to investigate QCD and Electroweak theories. The hot early universe is believed to have consisted of a quark vapor that underwent a phase transition to form quark condensates and hadrons. We are studying the structure of these condensates as revealed in the properties of hadrons, to be tested at Jefferson Laboratory and other medium energy accelerators. Our studies of the weak nuclear force investigates aspects of quark condensates analagous to the susceptibility of ferromagnets. In collaborations with Chinese theorists we study glueballs, quarkless hadrons, to be tested at accelerators in the U.S., China and Europe. We are investigating hadrons at high temperature, with the hope that some characteristics of the early universe phase transition can be observed at the RHIC accelerator. As part of this research we develop models which can be used in the analysis of medium energy experiments.
