Investigating the effects of Lorentz Invariance Violation on the CP-sensitivities of the Deep Underground Neutrino Experiment [PDF]
European Physical Journal C: Particles and Fields, 2023 The phenomena of neutrino oscillations offer a great potential for probing new-physics beyond the Standard Model. Any additional effects on neutrino oscillations can help understand the nature of the non-standard effects.

Constraining Lorentz invariance violation with next-generation long-baseline experiments [PDF]
Journal of High Energy Physics, 2023 Unified theories such as string theory and loop quantum gravity allow the Lorentz Invariance Violation (LIV) at the Planck Scale (M P ~ 1019 GeV). Using an effective field theory, this effect can be observed at low energies in terms of new interactions ...

Searching Lorentz invariance violation from cosmic photon attenuation [PDF]
European Physical Journal C: Particles and Fields, 2023 Lorentz invariance violation (LIV) can change the threshold behavior predicted by special relativity and cause threshold anomalies which affect the propagation of cosmic photons.

Possible Evidence for Lorentz Invariance Violation in Gamma-Ray Burst 221009A [PDF]
The Astrophysical Journal Letters, 2023 The preliminary detections of the gamma-ray burst 221009A up to 18 TeV by LHAASO and up to 251 TeV by Carpet 2 have been reported through Astronomer’s Telegrams and Gamma-ray Coordination Network circulars.

Lorentz Invariance Violation from Gamma-Ray Bursts
The Astrophysical JournalLorentz invariance violation (LV) is examined through the time delay between high-energy and low-energy photons in gamma-ray bursts (GRBs). Previous studies determined the LV energy scale as E _LV ≃ 3.60 × 10 ^17 GeV using Fermi Gamma-ray Space Telescope

Probing Lorentz Invariance Violation with atmospheric neutrinos at INO-ICAL [PDF]
Journal of High Energy Physics, 2022 The possibility of Lorentz Invariance Violation (LIV) may appear in unified theories, such as string theory, which allow the existence of a new space-time structure at the Planck scale (M p ∼ 1019 GeV).

Investigating Lorentz Invariance Violation with the long baseline experiment P2O [PDF]
Journal of High Energy Physics, 2023 One of the basic propositions of quantum field theory is Lorentz invariance. The spontaneous breaking of Lorentz symmetry at a high energy scale can be studied at low energy extensions like the Standard model in a model-independent way through effective ...

Probing for Lorentz Invariance Violation in Pantheon Plus Dominated Cosmology [PDF]
UniverseThe Hubble tension in cosmology is not showing signs of alleviation and thus, it is important to look for alternative approaches to it. One such example would be the eventual detection of a time delay between simultaneously emitted high-energy and low ...

Lorentz invariance violation limits from GRB 221009A [PDF]
Physical Review D, 2023 It has been long conjectured that a signature of Quantum Gravity will be Lorentz Invariance Violation (LIV) that could be observed at energies much lower than the Planck scale. One possible signature of LIV is an energy-dependent speed of photons.

Revisiting Lorentz invariance violation from GRB 221009A [PDF]
Journal of Cosmology and Astroparticle Physics, 2023 As a potential consequence of Lorentz invariance violation (LIV), threshold anomalies open a window to study LIV. Recently the Large High Altitude Air Shower Observatory (LHAASO) reported that more than 5000 photons from GRB 221009A have been observed ...
