具有物理夸克质量的QCD中的热凝聚

Thermal monopole condensation in QCD with physical quark masses

Marco Cardinali, Massimo D'Elia, Andrea Pasqui

摘要:

在$N_f = 2+1$ QCD中研究了热磁单极子的物理性质。在纯规范理论中,包裹数的分布表明凝聚温度与去禁闭温度相一致,而在这种情况下,包裹数的分布则表明约为275 MeV,几乎是QCD交叉温度$T_c$的两倍;类似的迹象也出现在寻找凝聚电流团的形成中。讨论了与上述$T_c$观测到的其它非微扰现象的可能关系。

英文摘要:

Thermal monopoles, identified after Abelian projection as magnetic currents wrapping non-trivially around the thermal circle, are studied in $N_f = 2+1$ QCD at the physical point. The distribution in the number of wrappings, which in pure gauge theories points to a condensation temperature coinciding with deconfinement, points in this case to around 275 MeV, almost twice the QCD crossover temperature $T_c$; similar indications emerge looking for the formation of a percolating current cluster. The possible relation with other non-perturbative phenomena observed above $T_c$ is discussed.
