Higher-derivative Lorentz-breaking terms in extended QED at the finite temperature
arXiv:1602.02570 · doi:10.1103/PhysRevD.93.065012
Abstract
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.
