We consider here the possibility of quantum gravity induced violation of Lorentz symmetry (LV). Even if suppressed by the inverse Planck mass such LV can be tested by current experiments and astrophysical observations. We review the effective field theory approach to describing LV, the issue of naturalness, and many phenomena characteristic of LV. We discuss some of the current observational bounds on LV, focusing mostly on those from high energy astrophysics in the QED sector at order E/M_Planck. In this context we present a number of new results which include the explicit computation of rates of the most relevant LV processes, the derivation of a new photon decay constraint, and modification of previous constraints taking proper account of the helicity dependence of the LV parameters implied by effective field theory.

  1. Constraining Lorentz invariance violation from the depth of air-shower maximum

    astro-ph.HE 2026-08 conditional novelty 6.0 of 10

    A simulation-based toy analysis of Auger Xmax data yields M_LIV > 1.5e21 GeV (95% CL) for subluminal photon-sector Lorentz invariance violation, subject to simplified detector and composition assumptions.

  2. Primordial black hole in Lorentz-violating theories: Insights from Bumblebee gravity

    gr-qc 2026-07 conditional novelty 6.0 of 10

    Bumblebee gravity enhances primordial black hole abundance through three mechanisms, but the model harbors a ghost instability and a tachyonic instability that make it cosmologically unviable.

  3. Vacuum Cherenkov radiation for nonminimal dimension-5 Lorentz violation

    hep-ph 2025-08 conditional novelty 6.0 of 10

    Isotropic dimension-5 Lorentz violation in fermions is constrained to below 1e-18 GeV^-1 (proton, m-type) and 3e-28 GeV^-1 (proton, a-type) by the absence of vacuum Cherenkov radiation in cosmic rays.

  4. Scattering Amplitudes and Resonant Processes in QED with Chiral Chemical Potential and Chiral Magnetic Conductivity

    hep-ph 2026-06 unverdicted novelty 5.0 of 10

    QED scattering amplitudes in a chiral medium with constant μ5 and b0 exhibit resonant behavior in multiple processes, with computed rates for 1→2 processes determining widths of fermion and photon states.

  5. Kinematical correlations via $\kappa$-Poincar\'e coproducts

    hep-th 2026-06 unverdicted novelty 5.0 of 10

    In the classical basis the non-bijective momentum map induces branch-dependent κ-deformed back-to-back correlations for two-particle states obeying vanishing total momentum.
