The program of research will focus on strong CP problem. It is one of the unresolved theoretical puzzles of the Standard Model of particle physics. In the first stage of the project, analytic and numerical studies of the analog of the CP problem in two-dimensional models will be performed with the aim of gaining insight into a possible dynamical solution. The second stage of the project will focus on the situation for pure Yang-Mills theories in four dimensions. The work may lead to further insight into the quantum structure of Quantum Chromodynamics. It might also affect the direction of future axion searches by experimentalists.

研究计划将集中在强CP问题。这是粒子物理学标准模型尚未解决的理论难题之一。在项目的第一阶段，将对二维模型中CP问题的模拟进行分析和数值研究，目的是深入了解可能的动态解决方案。该项目的第二阶段将重点关注四维纯杨米尔斯理论的情况。这一工作将有助于进一步了解量子色动力学的量子结构。这也可能影响实验学家未来对轴子的研究方向。
