论文摘要
我们使用NNLO HTLPT示点的热力学潜力介绍了QCD相变线的二阶和四阶曲率系数的预测。我们提出三种情况，与（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_l=μ__b/3 $。在所有三种情况下，鉴于当前的统计不确定性，我们都发现与连续的推断晶格QCD结果均为$κ_2$。在所有三种情况下，我们还对$κ_4$进行HTLPT预测，在可用的情况下再次与该系数的晶格提取再次达成了极好的一致性。
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.
