有限温度下扩展的QED中的高阶导数Lorentz破缺项

Higher-derivative Lorentz-breaking terms in extended QED at the finite temperature

A. Celeste, T. Mariz, J. R. Nascimento, A. Yu. Petrov

摘要:

本文讨论了在有限温度下,具有磁耦合的扩展QED中高阶导数Lorentz破缺项的有限性和模糊性。我们发现,除了高阶导数的Carroll-Field-Jackiw类项和Myers-Pospelov项之外,在有限温度情况下还出现了许多新项,但大多数项在高温极限下消失。

英文摘要:

In this paper we discuss finiteness and ambiguities of the higher-derivative Lorentz-breaking terms in extended QED with a magnetic coupling at the finite temperature. We find that, beside of the higher-derivative Carroll-Field-Jackiw-like term and Myers-Pospelov term, many new terms arise in a finite temperature case, but most of them vanish in high temperature limit.
