This project aims to disclose the composition of proton excited states by advancing the theoretical formalism governing the underlying dynamics. At present, the structure of even the first excited state of the proton, the Roper, remains unknown for more than 50 years following its discovery. While the fundamental theory of Quantum Chromodynamics (QCD) describes the interactions between the quarks and gluons composing these states, the phenomena that emerge from QCD are complex and require dedicated analyses to understand them. The intended outcome is the creation of the effective field theory required to decipher QCD calculations.

该项目旨在通过推进控制潜在动力学的理论形式来揭示质子激发态的组成。目前，即使是质子的第一激发态罗珀的结构，在发现后的50多年里仍然未知。虽然量子色动力学（QCD）的基本理论描述了构成这些状态的夸克和胶子之间的相互作用，但QCD中出现的现象非常复杂，需要专门的分析来理解它们。预期的结果是建立有效场论来破译QCD计算。
