1. Quantum aspects of the higher-derivative Lorentz-breaking extension of QED / Mariz, T. ; Nascimento, J. R. ; Petrov, A. Yu. ; Reyes, C. Marat
We consider the higher-derivative Lorentz-breaking extension of QED, where the new terms are the Myers-Pospelov-like ones in gauge and spinor sectors, and the higher–derivative Carroll-Field-Jackiw term. [...]
