基本荷电标量场朗道规范杨-米尔斯理论的红外行为

Infrared Behaviour of Landau Gauge Yang-Mills Theory with a Fundamentally Charged Scalar Field

Leonard Fister

摘要:

本文用Dyson-Schwinger方程研究了SU(N)基本表象中带电标量场的Yang-Mills理论的n点函数的红外行为。假设骨架展开是稳定的,得到了格林函数的幂律形式的解。对于无质量的标量场,均匀极限足以描述顶点的红外标度行为。不考虑可能的希格斯相,原来,运动学奇点起着重要的作用,大规模标量的标度解。在定性水平上,标量杨-米尔斯理论产生了类似的标度解,最近获得的QCD。

英文摘要:

The infrared behaviour of the n-point functions of a Yang-Mills theory with a charged scalar field in the fundamental representation of SU(N) is studied in the formalism of Dyson-Schwinger equations. Assuming a stable skeleton expansion solutions in form of power laws for the Green functions are obtained. For a massless scalar field the uniform limit is sufficient to describe the infrared scaling behaviour of vertices. Not taking into account a possible Higgs-phase it turns out that kinematic singularities play an important role for the scaling solutions of massive scalars. On a qualitative level scalar Yang-Mills theory yields similar scaling solutions as recently obtained for QCD.
