手征相变中π介子效应的研究

Studying pion effects on the chiral phase transition

J. A. Mueller, C. S. Fischer

摘要:

利用Dyson-Schwinger方程研究了有限温度零化学势下的手征相变。我们的夸克-胶子相互作用截断包括介子自由度,这使我们能够研究的相变的性质的π介子的影响。在本方案中,我们发现了百分之五的变化的临界温度由于π反反应,而平均场的过渡字符没有改变。

英文摘要:

We investigate the chiral phase transition at finite temperatures and zero chemical potential with Dyson-Schwinger equations. Our truncation for the quark-gluon interaction includes mesonic degrees of freedom, which allows us to study the impact of the pions on the nature of the phase transition. Within the present scheme we find a five percent change of the critical temperature due to the pion backreaction whereas the mean field character of the transition is not changed.
