摘要:

本文利用AdS/QCD对偶性计算了热Yang-Mills理论中剪切算符T_12的有限温度格林函数G(ω,k; T),对所有的ω,k。我们的目标是评估如何存在的尺度,如转变温度和胶球质量影响的关联函数计算的scalefree共形N = 4超对称杨米尔斯理论。我们观察到相当大的影响,T接近T_c,迅速消失,随着T的增加。这些预测与未来的晶格蒙特卡罗数据的定量一致性表明,在这个温度范围内的QCD物质是强相互作用的。

英文摘要:

We use AdS/QCD duality to compute the finite temperature Green's function G(omega,k;T) of the shear operator T_12 for all omega,k in hot Yang-Mills theory. The goal is to assess how the existence of scales like the transition temperature and glueball masses affects the correlator computed in the scalefree conformal N=4 supersymmetric Yang-Mills theory. We observe sizeable effects for T close to T_c which rapidly disappear with increasing T. Quantitative agreement of these predictions with future lattice Monte Carlo data would suggest that QCD matter in this temperature range is strongly interacting.
