Searches for anisotropies due to Earth's motion relative to a preferred frame -- modern versions of the Michelson-Morley experiment -- provide precise verifications of special relativity. We describe other tests, independent of this motion, that are or can become even more sensitive. The existence of high-energy cosmic rays places strong constraints on Lorentz non-invariance. Furthermore, if the maximum attainable speed of a particle depends on its identity, then neutrinos, even if massless, may exhibit flavor oscillations. Velocity differences far smaller than any previously probed can produce characteristic effects at accelerators and solar neutrino experiments.

  1. A Material Frame: Hard Recoils from Slow Force Carriers

    hep-ph 2026-07 conditional novelty 7.0 of 10

    Making the photon's longitudinal mode a physical, ultra-slow particle turns gauge invariance into a smooth limit and predicts rare, hard recoils of charges against a preferred frame, bounded to c_L ≲ 10^-60 by xenon d...

  2. 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.

  3. Spherical photon orbits around the Kerr-like black hole in Einstein-Bumblebee gravity

    gr-qc 2025-07 conditional novelty 5.0 of 10

    In Einstein-Bumblebee Kerr-like spacetimes, spherical photon orbits are governed by a sixth-order polynomial whose roots and critical inclination angle depend on the Lorentz-violation parameter.

  4. TeV-PeV Gamma-ray and Neutrino Emission in the Galactic Plane

    astro-ph.HE 2026-06 unverdicted novelty 3.0 of 10

    Alternative ISRF models produce only modest changes to the LHAASO diffuse gamma-ray fit; the associated pp neutrinos remain consistent with IceCube all-sky data and compatible with ANTARES/KM3NeT limits.
