本文介绍了高温QCD空间关联函数的研究进展。本文利用N_s=32$格点上的畴壁费米子和不同质量的夸克研究了N_f=2$ QCD中的等矢量介子算符。以前已经发现,在$\sim 2T_c$,这些观测值不仅是手征对称的,而且近似SU(2)_{CS}$和SU(4)$对称。在这项研究中,我们将温度提高到$5T_c$,并可以确定收敛到一个渐近自由的情况下,在非常高的温度。
We report on the progress of understanding spatial correlation functions in high temperature QCD. We study isovector meson operators in $N_f=2$ QCD using domain-wall fermions on lattices of $N_s=32$ and different quark masses. It has previously been found that at $\sim 2T_c$ these observables are not only chirally symmetric but in addition approximately $SU(2)_{CS}$ and $SU(4)$ symmetric. In this study we increase the temperature up to $5T_c$ and can identify convergence towards an asymptotically free scenario at very high temperatures.
