NNLO HTLpt predictions for the curvature of the QCD phase transition line
摘要：
我们提出的预测的第二和第四阶曲率系数的QCD相变线使用NNLO HTLpt的热力学势。我们提出了三个病例，分别对应于（i）$μ_s = μ_l = μ_B/3$，（ii）$μ_s=0$，$μ_l = μ_B/3,$和（iii）$S = 0$，$Q/B = 0.4$，$μ_l = μ_B/3$。在所有这三种情况下，我们发现很好的协议与连续外推晶格QCD结果$κ_2$，目前的统计不确定性。我们也使HTLpt预测$κ_4$在所有三种情况下，再次找到良好的协议与晶格提取这个系数可用。
英文摘要：
We present predictions for the second- and fourth-order curvature coefficients of the QCD phase transition line using the NNLO HTLpt-resummed thermodynamic potential. We present three cases corresponding to (i) $μ_s = μ_l = μ_B/3$, (ii) $μ_s=0$, $μ_l = μ_B/3,$ and (iii) $S = 0$, $Q/B = 0.4$, $μ_l = μ_B/3$. In all three cases, we find excellent agreement with continuum extrapolated lattice QCD results for $κ_2$, given current statistical uncertainties. We also make HTLpt predictions for $κ_4$ in all three cases, finding again excellent agreement with lattice extractions of this coefficient where available.
