  Light pseudoscalars, or axion like particles (ALPs), are much studied due to
their potential relevance to the fields of particle physics, astrophysics and
cosmology. The most relevant coupling of ALPs from the viewpoint of current
experimental searches is to the photon: in this work, we study the generation
of this coupling as an effect of quantum corrections, originated from an
underlying Lorentz violating background. Most interestingly, we show that the
interaction so generated turns out to be Lorentz invariant, thus mimicking the
standard ALPs coupling to the photon that is considered in the experiments.
This consideration implies that violations of spacetime symmetries, much
studied as possible consequences of physics in very high energy scales, might
infiltrate in other realms of physics in unsuspected ways. Additionally, we
conjecture that a similar mechanism can also generate Lorentz invariant
couplings involving scalar particles and photons, playing a possible role in
the phenomenology of Higgs bosons.
