AI总结:

本文研究了Curci-Ferrari模型中纯杨-米尔斯理论的去束缚相变,探讨了重整化尺度和方案对相变温度的影响,并验证了该模型在描述红外区域杨-米尔斯理论的有效性。

摘要:

我们分析了在中心对称Landau规范场框架下,纯杨-米尔斯理论的束缚/去束缚相变。该框架补充了一个Curci-Ferrari质量项,用于模拟与红外区域相关的Gribov复本的影响。除了为先前的一阶计算提供细节外,我们还探讨了结果如何依赖于重整化尺度和/或重整化方案。我们发现,预测的SU(2)和SU(3)杨-米尔斯理论的相变温度值在两种方案中相似,并且在广泛的尺度范围内对重整化尺度μ不太敏感,包括标准范围μ∈[πT,4πT]。这些值也接近通过最小敏感性原理获得的值,以及格点模拟的结果,尤其是在SU(3)的情况下。这些结果进一步确认了在Curci-Ferrari模型中微扰计算的良好行为,并支持后者作为杨-米尔斯理论红外有效描述的充分性。我们对SU(3)情况下的临界温度以及聚变环,即与中心对称性破缺相关的序参量进行了类似的分析。

英文摘要:

We analyze the confinement/deconfinement transition of pure Yang-Mills theories within the framework of the center-symmetric Landau gauge supplemented by a Curci-Ferrari mass term that models the effect of the associated Gribov copies in the infrared. In addition to providing details for earlier one-loop calculations in that framework, we explore how the results depend on the renormalization scale and/or on the renormalization scheme. We find that the predicted values for the transition temperatures of SU($2$) and SU($3$) Yang-Mills theories are similar in both schemes and are little sensitive to the renormalization scale $μ$ over a wide range of values including the standard range $\smash{μ\in[πT,4πT]}$. These values are also close both to those obtained from a minimal sensitivity principle and to those of lattice simulations, especially in the SU($3$) case. These results further confirm the good behavior of perturbative calculations within the Curci-Ferrari model and support the adequacy of the latter as an effective description of Yang-Mills theories in the infrared. We perform a similar analysis for the spinodal temperatures in the SU($3$) case and for the Polyakov loop, the order parameter associated to the breaking of center symmetry.
