Landau规范Yang-Mills理论中红外渐近的唯一性II

Uniqueness of infrared asymptotics in Landau gauge Yang-Mills theory II

Christian S. Fischer, Jan M. Pawlowski

摘要:

本文给出了朗道规范Yang-Mills理论中格林函数红外渐近标度解唯一性的证明\cite{Fischer:2006vf}的一个简化证明。简化涉及到一个新的RG不变的安排适用于一般理论的格林函数。和以前一样,证明依赖于戴森-施温格方程(DSE)和泛函重整化群方程(FRG)之间的必要一致性。我们还证明了存在一个特定的缩放解决方案,DSE和FRG,显示均匀和软运动学奇点。

英文摘要:

We present a shortened and simplified version of our proof \cite{Fischer:2006vf} of the uniqueness of the scaling solution for the infrared asymptotics of Green functions in Landau gauge Yang-Mills theory. The simplification relates to a new RG-invariant arrangement of Green functions applicable to general theories. As before the proof relies on the necessary consistency between Dyson-Schwinger equations (DSEs) and functional renormalisation group equations (FRGs). We also demonstrate the existence of a specific scaling solution for both, DSEs and FRGs, that displays uniform and soft kinematic singularities.
