Query: Quantization of the Myers-Pospelov model: the photon sector interacting
  with standard fermions as a perturbation of QED   We study the quantization of the electromagnetic sector of the Myers-Pospelov
model coupled to standard fermions. Our main objective, based upon experimental
and observational evidence, is to construct an effective theory which is a
genuine perturbation of QED, such that setting zero the Lorentz invariance
violation parameters will reproduce it. To this end we provide a physically
motivated prescription, based on the effective character of the model,
regarding the way in which the model should be constructed and how the QED
limit should be approached. This amounts to the introduction of an additional
coarse-graining physical energy scale $M$, under which we can trust the
effective field theory formulation. The prescription is successfully tested in
the calculation of the Lorentz invariance violating contributions arising from
the electron self-energy. Such radiative corrections turn out to be properly
scaled by very small factors for any reasonable values of the parameters and no
fine-tuning problems are found. Microcausality violations are highly suppressed
and occur only in a space-like region extremely close to the light-cone. The
stability of the model is guaranteed by restricting to concordant frames
satisfying $1-|\mathbf{v}_{max}|> 6.5\times10^{-11}$.
