论文摘要
我们从数值上研究纵向和横向gluon传播器之间差异的依赖性，$δ= d_l-d_t $，在$ t \ gtrsim t_c $ s su（2）和su（2）和su（3）gluodrodynalics中的动量和温度上。已经发现，相对于3摩诺特的$δ$的积分仅对红外动力学敏感，并且与polyakov环的相关性很大。在$ t = t_p \ sim 1.2 t_c $它更改标志，提供了一些证据，证明$ t_p $可以用作后汇款域的边界。
We study numerically the dependence of the difference between the longitudinal and transverse gluon propagators, $Δ=D_L-D_T$, on the momentum and temperature at $T\gtrsim T_c$ both in SU(2) and SU(3) gluodynamics. It is found that the integral of $Δ$ with respect to the 3-momentum is sensitive only to infrared dynamics and shows a substantial correlation with the Polyakov loop. At $T=T_p\sim 1.2 T_c$ it changes sign giving some evidence that $T_p$ can serve as a boundary of the postconfinement domain.
