LORENTZ VIOLATION EFFECTS ON ASTROPHYSICAL PROPAGATION OF VERY HIGH ENERGY PHOTONS
LORENTZ VIOLATION EFFECTS ON ASTROPHYSICAL PROPAGATION OF VERY HIGH ENERGY PHOTONS
Lorentz violation (LV) is predicted by some quantum gravity (QG) candidates, wherein the canonical energy-momentum dispersion relation, $E^2=p^2+m^2$, is modified. Consequently, new phenomenons beyond the standard model are predicted. Especially, the presence of LV highly affects the propagation of astrophysical photons with very high energies from distant galaxies. In this …
