From special relativity, photon annihilation process γγ→e+e− prevents cosmic photons with energies above a threshold to propagate a long distance in cosmic space due to their annihilation with low energy cosmic background photons. However, modifications of the photon dispersion relation from Lorentz invariance violation (LIV) can cause novel phenomena beyond special relativity to happen. In this paper, we point out that these phenomena include optical transparency, threshold reduction and… Expand

LHAASO discovery of highest energy photons towards new physics
Ultrahigh-energy photons up to 1.4 peta-electronvolts have been observed by new cosmic-ray telescope in China [1] – a hint that Lorentz invariance might break down at the Planck-scale level [2].

Lorentz violation from gamma-ray bursts
The constancy of light speed is a basic assumption in Einstein’s special relativity, and consequently the Lorentz invariance is a fundamental symmetry of space–time in modern physics. However, it isExpand
