Ultrahigh-energy photons from LHAASO as probes of Lorentz symmetry violations
The Large High Altitude Air Shower Observatory (LHAASO) is one of the most sensitive gammaray detector arrays currently operating at TeV and PeV energies. Recently the LHAASO experiment detected
Ultrahigh-energy photons up to 1.4 petaelectronvolts from 12 γ-ray Galactic sources.
The detection of more than 530 photons at energies above 100 teraelectronvolts and up to 1.4 PeV from 12 ultrahigh-energy γ-ray sources with a statistical significance greater than seven standard deviations is reported.

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
Light speed variation from gamma ray burst GRB 160509A
Abstract It is postulated in Einstein's relativity that the speed of light in vacuum is a constant for all observers. However, the effect of quantum gravity could bring an energy dependence of light
Lorentz violation (LV) is predicted by some quantum gravity (QG) candidates, wherein the canonical energy–momentum dispersion relation, E2 = p2+m2, is modified. Consequently, new phenomena beyond the
Introduction to Large High Altitude Air Shower Observatory (LHAASO)
Abstract Since the century discovery of cosmic ray, the origin of cosmic ray is always a mystery. The study on the origin of high-energy cosmic ray is in an interdiscipline between the very
Light speed variation from gamma-ray bursts
Abstract The effect of quantum gravity can bring a tiny light speed variation which is detectable through energetic photons propagating from gamma ray bursts (GRBs) to an observer such as the space
Regularity of high energy photon events from gamma ray bursts
The effect of Quantum Gravity (QG) may bring a tiny light speed variation as $v(E)=c(1-E/E_{\rm LV})$, where $E$ is the photon energy and $E_{\rm LV}$ is a Lorentz violation scale. A remarkable
Light speed variation with brane/string-inspired space-time foam
Abstract Recently a series of studies on high energy gamma-ray burst (GRB) photons suggested a light speed variation with linear energy dependence at the Lorentz violation scale of 3 . 6 × 1 0 17 GeV
Derivation of a Vacuum Refractive Index in a Stringy Space-Time Foam Model
Abstract It has been suggested that energetic photons propagating in vacuo should experience a non-trivial refractive index due to the foamy structure of space–time induced by quantum-gravitational
