基于QCD的胶子凝聚有效模型

Effective model based on QCD with gluon condensate

Hiroaki Kohyama

摘要:

我们构造了基于QCD的胶子凝聚的有效模型。在假设胶子在动量空间中以尖锐的动量峰凝聚的前提下,建立了包含胶子凝聚和手征凝聚的有效场论,并研究了两种凝聚在温度和化学势平面上的相变.我们发现凝聚量随温度的升高而减少,这是可靠的趋势,凝聚量与渐近行为的论点是一致的。

英文摘要:

We construct the effective model based on QCD with gluon condensate. Under the assumption that the gluons are condensed with the sharp momentum peak in the momentum space, we formulate the effective field theory incorporating both the gluon condensate and the chiral condensate, then study the phase transition on temperature and chemical potential plane with respect to two condensates. We find that the condensates decrease with increasing temperature, which is reliable tendency on the condensate being consistent with the argument of the asymptotic behavior.
