有限温度和密度QCD中有效夸克质量的研究

Effective quark mass at finite temperature and density QCD

利用有限温度量子色动学的实时形式 ,研究了有限温度和密度条件下的有效夸克质量 .结果表明 ,有效夸克质量随温度的增加而迅速增加 ,而在夸克质量中的密度效应只是在低温区域才是重要的 ,且在给定的密度 。

The effective quark mass at finite temperature and density is studied by u sing the real-time formalism of finite temperature QCD. It is shown that the e ff ective quark mass is significent only in low temperature regions, and in a given density, the effective quark mass has a minmum at a small temperature.
