The project will study the dynamics of gauge theorieswith symplectic gauge group. The general aims are to predict the properties of the composite states of the theory, and to characterise theconfinement phase transition, as a function of the temperature of the system.Alternative scenarios will be considered, in which the gauge theory is taken in isolation,or in the presence of matter fields with different transformation properties in respect to the gauge group.Potential applications are mostly within fundamental physics, ranging from short distance characterisation of new physics models,to contemporary astroparticle phsyics (dark matter),to more speculative early-universe scenarios (gravitational wave backgrounds).

本课题将用辛规群研究规理论的动力学。总的目标是预测理论复合态的性质，并描述约束相变作为系统温度的函数。将考虑替代方案，在这些方案中，规范理论被孤立地考虑，或者存在与规范群相关的具有不同变换特性的物质场。潜在的应用主要是在基础物理学中，从新物理模型的短距离表征，到当代天体粒子物理学（暗物质），再到更推测的早期宇宙场景（引力波背景）。
