论文摘要
我们考虑了“大规模背景Landau仪表”的BRST不变概括，类似于原始的Curci-Ferrari模型，该模型由于其在建模红外Yang-Mills动力学上的现象学上的成功而看到了恢复的兴趣，包括相位过渡。但是，与Curci-Ferrari模型不同，质量参数不再是现象学输入，而是通过BRST不变尺寸的两个Gluon Condementate进入尺寸trans变的结果。相关的重归其化常数是使用Zimmermann的减少常数程序来处理的，该程序将质量参数的值固定到接近curci-Ferrari方法中的值的值。使用自一致的背景字段，我们可以包括Polyakov环路并探测解封型跃迁，包括其与冷凝物的相互作用及其电磁不对称性。我们在SU（2）情况下报告了TC〜0.230 GEV的连续相变，在SU（3）情况下，在TC〜0.164 GEV处的一阶ter阶透明，值再次接近curci-ferrari模型中以一环阶的速度获得的值。
We consider a BRST invariant generalization of the "massive background Landau gauge", resembling the original Curci-Ferrari model that saw a revived interest due to its phenomenological success in modeling infrared Yang-Mills dynamics, including that of the phase transition. Unlike the Curci-Ferrari model, however, the mass parameter is no longer a phenomenological input but it enters as a result of dimensional transmutation via a BRST invariant dimension two gluon condensate. The associated renormalization constant is dealt with using Zimmermann's reduction of constants program which fixes the value of the mass parameter to values close to those obtained within the Curci-Ferrari approach. Using a self-consistent background field, we can include the Polyakov loop and probe the deconfinement transition, including its interplay with the condensate and its electric-magnetic asymmetry. We report a continuous phase transition at Tc ~ 0.230 GeV in the SU(2) case and a first order one at Tc ~ 0.164 GeV in the SU(3) case, values which are again rather close to those obtained within the Curci-Ferrari model at one-loop order.
