Impact of cosmology on Lorentz Invariance Violation constraints from GRB time-delays [PDF]
Classical and quantum gravity, 2023 Putting constraints on a possible Lorentz Invariance Violation (LIV) from astrophysical sources such as gamma-ray bursts (GRBs) is essential for finding evidences of new theories of quantum gravity (QG) that predict an energy-dependent speed of light ...

Searches for Lorentz Invariance Violation at the Pierre Auger Observatory [PDF]
EPJ Web of Conferences, 2023 Lorentz Invariance (LI) requires the space-time structure to be the same for all observers, but various quantum gravity theories suggest that it may be violated when approaching the Planck scale. Even a small violation of LI could easily affect the Ultra-

Testing Lorentz invariance violation using cosmogenic neutrinos [PDF]
International Conference on Rebooting Computing, 2023 Secondary messengers such as neutrinos and photons are expected to be produced in interactions of ultra-high-energy cosmic rays (UHECRs) with extragalactic background photons.

On the lightlike Lorentz violation
Physics Letters B, 2020 We consider the lightlike spontaneous Lorentz invariance violation (SLIV) appearing through the zero “length-fixing” constraint put on a gauge vector field, AμAμ=0, and discuss its physical consequences in the framework of a conventional QED and beyond ...

Spectral Lag Transition of 32 Fermi Gamma-Ray Bursts and Their Application on Constraining Lorentz Invariance Violation [PDF]
Astrophysical Journal, 2022 The positive-to-negative transition of spectral lag is an uncommon feature reported in a small number of gamma-ray bursts (GRBs). An application of such a feature has been made to constrain the critical quantum gravity energy (E QG) of the light photons ...

Lorentz invariance violation and generalized uncertainty principle [PDF]
Physics of Particles and Nuclei Letters, 2016 There are several theoretical indications that the quantum gravity approaches may have predictions for a minimal measurable length, and a maximal observable momentum and throughout a generalization for Heisenberg uncertainty principle. The generalized uncertainty principle (GUP) is based on a momentum-dependent modification in the standard dispersion ...

Ultra-High-Energy Astroparticles as Probes for Lorentz Invariance Violation
Universe, 2022 Compelling evidence for Lorentz invariance violation (LIV) would demand a complete revision of modern physics. Therefore, searching for a signal or extending the validity of the invariance is fundamental for building our understanding of the extreme ...

Distinguishing nonstandard interaction and Lorentz invariance violation at the Protvino to super-ORCA experiment [PDF]
Physical Review D, 2022 As the two phenomena, non-standard interaction (NSI) in neutrino propagation and Lorentz invariance violation (LIV) modify the Hamiltonian of neutrino oscillation in a similar fashion, it is very difficult to distinguish these two effects.
