Tiny violations of the Lorentz symmetry of relativity and the associated discrete CPT symmetry could emerge in a consistent theory of quantum gravity such as string theory. Recent evidence for linear polarization in gamma-ray bursts improves existing sensitivities to Lorentz and CPT violation involving photons by factors ranging from ten to a million.

Lorentz Symmetry and High-Energy Neutrino Astronomy
The search of the violation of Lorentz symmetry, or Lorentz violation (LV), is an active research field. The effects of LV are expected to be very small, and special systems are often used to search
Neutrino interferometry for high-precision tests of Lorentz symmetry with IceCube
Lorentz symmetry is a fundamental spacetime symmetry underlying both the standard model of particle physics and general relativity. This symmetry guarantees that physical phenomena are observed to ...
Bounds on vacuum-orthogonal Lorentz and CPT violation from radiative corrections
Certain forms of Lorentz violation in the photon sector are difficult to bound directly, since they are "vacuum orthogonal," meaning they do not change the solutions of the equations of motion in
Signals for Lorentz violation in gravitational waves
Lorentz violations in gravitational waves are investigated. Plane-wave solutions for arbitrary gauge-invariant violations in linearized gravity are constructed. Signatures of Lorentz violation
Lorentz invariance violations in the interplay of quantum gravity with matter
We explore the interplay of matter with quantum gravity with a preferred frame to highlight that the matter sector cannot be protected from the symmetry-breaking effects in the gravitational sector.
Constraints on Lorentz Invariance Violation from Optical Polarimetry of Astrophysical Objects
Theories of quantum gravity suggest that Lorentz invariance, the fundamental symmetry of the Theory of Relativity, may be broken at the Planck energy scale. While any deviation from conventional

Top hadrons in Lorentz-violating field theory
If there is Lorentz symmetry violation in the $t$ quark sector of the standard model, changes to particles' dispersion relations might allow for the existence of stable top-flavored hadrons.
Non-Minimal Lorentz Violation in Macroscopic Matter
TLDR
The hamiltonian and modified Newton's second law for a test body are derived and the framework is applied to free-fall and torsion-balance tests of the weak equivalence principle and to orbital motion.
Tests of Lorentz Invariance Using High-Energy Astrophysics Observations
High-energy astrophysics observations provide the best possibilities to detect a very small violation of Lorentz invariance, such as may be related to the structure of space-time near the Planck

This work provides a systematic classification of renormalizable and nonrenormalizable operators for Lorentz violation in electrodynamics and uses polarimetric observations to search for the associated violations.

CPT violation implies violation of Lorentz invariance.
TLDR
A interacting theory that violates CPT invariance necessarily violates Lorentz invariance, and theories that violate CPT by having different particle and antiparticle masses must be nonlocal.
