Nambu-Jona-Lasinio模型的预测公式性质和鬼问题

Properties of predictive formulation of the Nambu-Jona-Lasinio model and ghost problem

V. E. Rochev

摘要:

最近提出的Battistel等人。“NJL模型的预测公式”进行了讨论,并指出其与微分正则化的连接。这个公式的主要问题是介子传播子的非物理奇点(朗道极点)。一个修改的制定,这是免费的朗道极点和保存的方法的主要特点,提出了。

英文摘要:

Recently proposed by Battistel et al. "predictive formulation of the NJL model" is discussed and its connection with the differential regularization is noted. The principal problem of this formulation is a non-physical singularity (Landau pole) in meson propagators. A modification of the formulation, which is free of the Landau pole and conserves main features of the approach, is proposed.
