T_c以下的胶子球、胶子凝聚和纯胶QCD

Glueballs, gluon condensate, and pure glue QCD below T_c

F. Buisseret

摘要:

本文提出了T<T_c时纯胶QCD热力学的准粒子描述,并与最近的格点数据进行了比较。考虑到具有恒定质量的胶球气体不能定量地再现解除禁闭相变的早期阶段,问题是确定导致观察到的压力突然增加、痕量异常、结果表明,T_c附近胶子凝聚的强烈减少和最轻胶球热宽度的增大可能是相变的触发因素。

英文摘要:

A quasiparticle description of pure glue QCD thermodynamics at T<T_c is proposed and compared to recent lattice data. Given that a gas of glueballs with constant mass cannot quantitatively reproduce the early stages of the deconfinement phase transition, the problem is to identify a relevant mechanism leading to the observed sudden increase of the pressure, trace anomaly, etc. It is shown that the strong decrease of the gluon condensate near T_c combined with the increasing thermal width of the lightest glueballs might be the trigger of the phase transition.
