摘要:

利用维数正则化方法研究了Nambu-Jona-Lasinio模型在温度-化学势平面上的相图。虽然所得到的图的结构与常用的截断正则化中的结构相似,但我们研究的一些结果表明这些正则化之间存在显着差异。维数正则化后的相图显示出强烈的一级相变趋势。

英文摘要:

We investigate the phase diagram on temperature-chemical potential plane in the Nambu-Jona-Lasinio model with the dimensional regularization. While the structure of the resulting diagram shows resemblance to the one in the frequently used cutoff regularization, some results of our study indicate striking difference between these regularizations. The diagram in the dimensional regularization exhibits strong tendency of the first order phase transition.
