Constraining Lorentz Violation with Cosmology [PDF]
Physical Review Letters, 2008 The Einstein-Aether theory provides a simple, dynamical mechanism for breaking Lorentz invariance. It does so within a generally covariant context and may emerge from quantum effects in more fundamental theories. The theory leads to a preferred frame and can have distinct experimental signatures.

Impact of Lorentz violation on anomalous magnetic moments of charged leptons
Journal of High Energy Physics, 2022 We address the question whether a violation of Lorentz symmetry can explain the tension between the measurement and the Standard-Model prediction of the anomalous magnetic moment of the muon, (g − 2)μ, and whether it can significantly impact the one of ...

Gravity from local Lorentz violation [PDF]
General Relativity and Gravitation, 2005 In general relativity, gravitational waves propagate at the speed of light, and so gravitons are massless. The masslessness can be traced to symmetry under diffeomorphisms. However, another elegant possibility exists: masslessness can instead arise from spontaneous violation of local Lorentz invariance. We construct the corresponding theory of gravity.

Beta-decay spectrum and Lorentz violation
Physics Letters B, 2022 Relativity theory and its underlying Lorentz and CPT invariance represent key principles of physics and therefore require continued experimental scrutiny across the broadest possible range of energy scales and physical systems. Possibilities for tests of

Neutrino telescope modelling of Lorentz invariance violation in oscillations of atmospheric neutrinos [PDF]
, 2008 One possible feature of quantum gravity may be the violation of Lorentz invariance. In this paper, we consider one particular manifestation of the violation of Lorentz invariance, namely modified dispersion relations for massive neutrinos.

On Lorentz violation in e− + e+ → μ− + μ+ scattering at finite temperature
Physics Letters B, 2019 Small violation of Lorentz and CPT symmetries may emerge in models unifying gravity with other forces of nature. An extension of the standard model with all possible terms that violate Lorentz and CPT symmetries are included.

Lorentz and CPT Invariance Violation In High-Energy Neutrinos [PDF]
, 2005 High-energy neutrino astronomy will be capable of observing particles at both extremely high energies and over extremely long baselines. These features make such experiments highly sensitive to the effects of CPT and Lorentz violation.

Proposed astrophysical test of Lorentz invariance [PDF]
, 1999 Working in the context of a Lorentz-violating extension of the standard model we show that estimates of Lorentz symmetry violation extracted from ultra-high energy cosmic rays beyond the Greisen-Kuzmin-Zatsepin (GZK) cutoff allow for setting bounds on ...
