Nuclear beta decay with Lorentz violation [PDF]
, 2013 We consider the possibility of Lorentz-invariance violation in weak-decay processes. We present a general approach that entails modifying the W-boson propagator by adding a Lorentz-violating tensor to it.

Lorentz-violating electrostatics and magnetostatics [PDF]
Physical Review D, 2004 The static limit of Lorentz-violating electrodynamics in vacuum and in media is investigated. Features of the general solutions include the need for unconventional boundary conditions and the mixing of electrostatic and magnetostatic effects. Explicit solutions are provided for some simple cases.

Universe, 2023 In search of physics beyond the standard model, new phenomena can be relevant in low energies. In view of the Standard Model Extension is an effective field theory, in this study we explore the fermionic sector by showing that the properties of ...

Neutrinos with Lorentz-violating operators of arbitrary dimension [PDF]
, 2012 The behavior of fermions in the presence of Lorentz and CPT violation is studied. Allowing for operators of any mass dimension, we classify all Lorentz-violating terms in the quadratic Lagrange density for free fermions.

Charged Lifshitz black hole and probed Lorentz-violation fermions from holography
Physics Letters B, 2017 We analytically obtain a new charged Lifshitz solution by adding a non-relativistic Maxwell field in Hořava–Lifshitz gravity. The black hole exhibits an anisotropic scaling between space and time (Lifshitz scaling) in the UV limit, while in the IR limit,

Lorentz violation, Gravitoelectromagnetism and Bhabha Scattering at finite temperature
, 2018 Gravitoelectromagnetism (GEM) is an approach for the gravitation field that is described using the formulation and terminology similar to that of electromagnetism.

Disentangling Forms of Lorentz Violation With Complementary Clock Comparison Experiments [PDF]
, 2009 Atomic clock comparisons provide some of the most precise tests of Lorentz and CPT symmetries in the laboratory. With data from multiple such experiments using different nuclei, it is possible to constrain new regions of the parameter space for Lorentz ...

Cross sections and lorentz violation [PDF]
Physics Letters B, 2001 The derivation of cross sections and decay rates in the Lorentz-violating standard-model extension is discussed. General features of the physics are described, and some conceptual and calculational issues are addressed. As an illustrative example, the cross section for the specific process of electron-positron pair annihilation into two photons is ...

CPT Violation Implies Violation of Lorentz Invariance [PDF]
, 2002 An interacting theory that violates CPT invariance necessarily violates Lorentz invariance. On the other hand, CPT invariance is not sufficient for out-of-cone Lorentz invariance.
