摘要:

我们考虑了杨-米尔斯理论中鬼场和胶子传播子的谱Dyson-Schwinger方程耦合组,这使我们能够获得鬼场和胶子谱函数。该设置用于对杨-米尔斯理论中广义谱表示约束进行系统的解析评估,这些约束对于有依据的谱重建最为相关。我们还提供了在胶子潜在质量间隙大范围内耦合谱函数组的数值结果,并讨论了当前工作的局限性和扩展方向。

英文摘要:

We consider the coupled set of spectral Dyson-Schwinger equations in Yang-Mills theory for ghost and gluon propagators, which gives us access to the ghost and gluon spectral functions. The set-up is used for a systematic analytic evaluation of the constraints on generalised spectral representations in Yang-Mills theory that are most relevant for informed spectral reconstructions. We also provide numerical results for the coupled set of spectral functions for a large range of potential mass gaps of the gluon, and discuss the limitations and extensions of the present work.
