Two-sided constraints on Lorentz Invariance violation from Tibet-AS$\gamma$ and LHAASO Very-High-Energy photon observations

TL;DR

This paper derives new limits on Lorentz Invariance violation energy scales for photons using recent gamma-ray observations, improving existing constraints and covering both superluminal and subluminal scenarios.

Contribution

It provides the strongest two-sided constraints on Lorentz Invariance violation energy scales from gamma-ray data, considering photon triple splitting and shower suppression effects.

Findings

Constraints in subluminal scenario surpass pair production limits.

New bounds are the most stringent in the literature.

Results apply to both superluminal and subluminal photon dispersion models.

Abstract

We present new two-sided constraints on Lorentz Invariance violation energy scale for photons with quartic dispersion relation from recent gamma ray observations by Tibet-AS$\gamma$ and LHAASO experiments. The constraints are based on the consideration of the processes of photon triple splitting (superluminal scenario) and the suppression of shower formation (subluminal). The constraints in subluminal scenario are better than the pair production constraints and are the strongest in the literature.
