论文摘要
为了在有限的巴属化学势下研究热QCD中的介子的命运，我们考虑使用泰勒膨胀到$ {\ cal o}（（（μ/t）^2）$，在Hadroonic和Quark-gluon plasma阶段中。我们使用$ n_f = 2+1 $ Wilson Fermion风味的快餐段固定尺度晶格。我们发现，间隔相关器对有限密度校正敏感，二阶项表示矢量和轴向矢量通道中的手性交叉。
In order to study the fate of mesons in thermal QCD at finite baryon chemical potential, we consider light mesonic correlation functions using the Taylor expansion to ${\cal O}((μ/T)^2)$, in both the hadronic and quark-gluon plasma phases. We use the FASTSUM anisotropic fixed-scale lattices with $N_f = 2+1$ flavours of Wilson fermion. We find that mesonic correlators are sensitive to finite-density corrections and that the second-order terms indicate the chiral crossover in the vector and axial-vector channels.
