Resumen
WE PROVIDE THE FIRST STEP TOWARDS RENORMALIZATION IN A NONMINIMAL LORENTZ-VIOLATING MODEL CONSISTING OF NORMAL SCALARS AND MODIFIED FERMIONS WITH MASS DIMENSION FIVE OPERATORS. WE COMPUTE THE RADIATIVE CORRECTIONS CORRESPONDING TO THE SCALAR SELF-ENERGY, AND WE SHOW THAT SOME DIVERGENCIES ARE IMPROVED AND IN THE SCALAR SECTOR THEY ARE FINITE. THE POLE MASS OF THE SCALAR TWO-POINT FUNCTION IS FOUND AND SHOWN TO LEAD TO MODIFICATIONS OF ASYMPTOTIC STATES.
