Electrodynamics Modified by Some Dimension-five Lorentz Violating Interactions: Radiative Corrections
We study radiative corrections to massless quantum electrodynamics modified
by two dimension-five LV interactions and in
the framework of effective field theories. All divergent
one-particle-irreducible Feynman diagrams are calculated at one-loop order and
several related issues are discussed. It is found that massless quantum
electrodynamics modified by the interaction alone is one-loop renormalizable and the result can be
understood on the grounds of symmetry. In this context the one-loop
Lorentz-violating beta function is derived and the corresponding running
coefficients are obtained.Comment: 13 pages, 1 figure. Version to appear in EPJ
