论文摘要
在非零温度下的非亚伯仪理论的脱合式制度中，以前有人认为，如果添加了（规格不变的）来源以产生非零的载体，则该源必须是针对小型全能的线性。最简单的例子是第二个Bernoulli多项式。但是，然后在耦合常数$ g $中将自由能计算为$ \ sim g^3 $的难题是不连续的，随着自动固体的消失。在本文中，我们动态地研究了第二种Bernoulli多项式生成的两种方式：作为辅助场的质量导数，以及从嵌入各向同性的二维幽灵中，以四个维度嵌入。计算Gluon自我能源中的自动硬热环（HHTL），我们发现小型固体的极限仅适用于两个维度的幽灵，其自由能，而自由能将$ \ sim g^3 $连续，而随着自灵的消失，它是连续的。
In the deconfined regime of a non-Abelian gauge theory at nonzero temperature, previously it was argued that if a (gauge invariant) source is added to generate nonzero holonomy, that this source must be linear for small holonomy. The simplest example of this is the second Bernoulli polynomial. However, then there is a conundrum in computing the free energy to $\sim g^3$ in the coupling constant $g$, as part of the free energy is discontinuous as the holonomy vanishes. In this paper we investigate two ways of generating the second Bernoulli polynomial dynamically: as a mass derivative of an auxiliary field, and from two dimensional ghosts embedded isotropically in four dimensions. Computing the holonomous hard thermal loop (HHTL) in the gluon self-energy, we find that the limit of small holonomy is only well behaved for two dimensional ghosts, with a free energy which to $\sim g^3$ is continuous as the holonomy vanishes.
