QCD相变及若干强子性质的研究

The property of strongly interacting matter and hadron physics are always frontier research fields focused by particle physics and nuclear physics community. In recent years, many related experimental equipments and detectors will be constructed or upgraded and put into operation. They will bring about great challenges and opportunities to the existing theories. The solution of many of the fundamental problems in hadron physics and QCD theory needs close coordination of theory and experiment.Therefore, the study of properties of excited states of nucleon, hadron form factors, parton distribution function, and other physical quantities have drawn wide attention. In addition, studies on QCD phase transitions can help us to understand the origin of the observable mass in the universe and the nature of the early universe, as well as the nature of neutron star. The nature of strong interaction phase transitions, the existence and location of CEP, the influence of strong external magnetic field on the relavant physical quantities and physical processes, and similar issues are also focuses of theoretical and experimental studies. This project intends to adopt Dyson-Schwinger equation approach, which has a good QCD foundation, to analyze and study the above related issues.

强相互作用物质的性质和强子物理一直都是粒子物理和核物理学界关注的前沿研究领域。近年来，有许多相关的实验设备与探测器即将完成建造或升级并投入运行，它们给现有理论带来了很大的挑战和机遇。解决强子物理和QCD中的众多基本问题需要理论和实验的密切配合。因此，激发态核子性质，强子的形状因子，部分子分布函数等物理量的研究引起了人们的广泛重视。此外，QCD相变的研究有助于理解宇宙中可观测质量的起源和早期宇宙的性质，以及有关中子星性质的讨论等。关于强相互作用相变的性质，CEP点的存在性及位置，强外磁场对相关物理量和物理过程的影响等问题也是理论和实验上研究的热点。本项目拟在有很好QCD基础的Dyson-Schwinger方程框架下，对上述相关问题进行分析探讨。
