The influence of Lorentz violation on UHE photon detection
Abstract
We show that violation of the Lorentz symmetry in quantum electrodynamics can
suppress the rates of the interactions crucial for the formation of
photon-induced air showers, such as pair production on nuclei and in the
geomagnetic field. As a consequence, the allowed region in the space of
Lorentz-violating parameters will be seriously restricted if several photons
with energies $\gtrsim\,10^{19}\, {eV}$ are detected.
