Atomic nuclei are made of neutrons and protons, which were previously thought to be elementary particles, but are now known to be themselves made up of quarks. This fundamental difference requires a new understanding of how the neutrons and protons bind to each other to make up nuclei. The effects of the extended size of nuclear particles have not yet been taken into account. The project will apply new equations in relativistic field theory, taking account of the particles' size, to analyze data on the processes which bind nuclei together.

原子核由中子和质子组成，以前被认为是基本粒子，但现在已知它们本身是由夸克组成的。 这种根本差异需要对中子和质子如何相互结合形成原子核有新的理解。 核粒子尺寸扩大的影响尚未考虑在内。 该项目将应用相对论场论中的新方程，考虑粒子的尺寸，来分析将原子核结合在一起的过程的数据。
