论文摘要
在SU（2）Gluodynemics中，Debye Gluon贡献W_D（A_0）对时间表场分量的有效作用A_0 = CONST在高温下计算在背景R^{XI}仪表中。结果表明，在非零A_0标准定义k_0 = 0，| k | - > 0对应于内部空间胶子中纵向的长距离相关。横向胶子被A_0背景字段筛选。因此，它们给出了零贡献，必须从相关校正中排除。一环，两环和正确的W_D（A_0）的总有效动作占了尼尔森的身份，证明了A_0缩合现象的规格不变性。
In SU(2) gluodynamics, the Debye gluon contribution W_D(A_0) to the effective action of the temporal gauge field component, A_0 = const, at high temperature is calculated in the background R^{xi} gauge. It is shown that at nonzero A_0 the standard definition k_0 = 0, |k| -> 0 corresponds to long distance correlations for the longitudinal in internal space gluons. The transversal gluons become screened by the A_0 background field. Therefore they give zero contributions and have to be excluded from the correlation corrections. The total effective action accounting for the one-loop, two-loop and correct W_D(A_0) satisfies Nielsen's identity that proves gauge invariance of the A_0 condensation phenomenon.
