夸克-胶子等离子体中的有限温度格点量子色动力学重子
Finite Temperature Lattice QCD - Baryons in the Quark-Gluon Plasma
摘要:
重子关联函数是研究宇称加倍和手征对称性的理想工具。我们提出了一个研究使用$2+1$口味的各向异性威尔逊三叶草费米子的FASTSUM合奏,并找到明确的证据,宇称加倍出现在夸克-胶子等离子体。这一结果是证实的频谱功能,这是使用MEM重建获得的水平。在这项研究中,我们进一步强调了高斯涂抹的重要性。
英文摘要:
Baryonic correlation functions provide an ideal tool to study parity doubling and chiral symmetry using lattice simulations. We present a study using $2+1$ flavors of anisotropic Wilson clover fermions on the FASTSUM ensembles and find clear evidence that parity doubling emerges in the quark-gluon plasma. This result is confirmed on the level of spectral functions, which are obtained using a MEM reconstruction. We further highlight the importance of Gaussian smearing in this study.
