Finsler geometry is a natural and fundamental generalization of Riemann geometry. The Finsler structure depends on both coordinates and velocities. We present the arrival time delay of astroparticles subject to Lorentz violation in the framework of Finsler geometry, and the result corresponds to that derived by Jacob and Piran in the standard model of cosmology.

  1. Monte Carlo simulation of GRB data to test Lorentz-invariance violation

    hep-ph 2025-04 conditional novelty 5.0 of 10

    A combined model with both Lorentz-violation and energy-dependent intrinsic delays recovers simulated parameters across all mock datasets and fits multi-GeV and TeV GRB photons, yielding a subluminal LV scale of about...

  2. Examining Lorentz invariance violation with three remarkable GRB photons

    astro-ph.HE 2025-04 conditional novelty 4.0 of 10

    Adding three extreme GRB photons preserves the fitted Lorentz-violation scale E_LV ~ 3e17 GeV, but only when an energy-dependent intrinsic delay term, itself a fitting construct, absorbs the new TeV photons.
