Resumen:

Radiative corrections in quantum field theories with small departures from Lorentz symmetry alter structural aspects of the theory, in particular the definition of asymptotic single-particle states. Specifically, the Dirac equation is radiatively modified by Lorentz-violating momentum-dependent operators not present in the Lagrange density, and the standard renormalization procedure needs to be adapted too. © 2014 by World Scientific Publishing Co.
