Structure of Hadronic Excitations from Lattice Quantum Chromodynamics

量子色动力学描述了夸克和胶子组成强子（如质子或中子）时的基本强相互作用。在这些最低能量系统之外，量子力学激发光谱显示出丰富而复杂的结构。值得注意的是，人们对这些状态的内部结构知之甚少。该项目的中心目标是利用晶格规范理论的第一性原理方法揭示强子及其激发态的性质。通过从最基本的非微扰夸克和胶子场的角度阐明强子结构的各个方面，该项目将为国际设施中著名的实验项目创造新的知识。

Quantum chromodynamics describes the fundamental strong interactions between quarks and gluons as they compose hadrons such as the proton or neutron. Beyond these lowest-energy systems, the quantum mechanical excitation spectra display a rich and complex structure. Remarkably, little is known about the internal structure of these states. The central goal of this project is to unveil the nature of hadrons and their excited states using the first principles approach of lattice gauge theory. By elucidating aspects of hadron structure in terms of the most fundamental non-perturbative quark and gluon fields, the project will create new knowledge impacting on renowned experimental programs at international facilities.
