Homogeneously Modified Special relativity (HMSR)
European Physical Journal C: Particles and Fields, 2019 This work explores a Standard Model extension possibility, that violates Lorentz invariance, preserving the space-time isotropy and homogeneity. In this sense HMSR represents an attempt to introduce an isotropic Lorentz Invariance Violation in the ...

Vortices, infrared effects and Lorentz invariance violation
Physics Letters B, 2006 La teoría de Yang-Mills con campos no conmutativos se construye siguiendo métodos hamiltonianos y lagrangeanos. Esta modificación de la teoría estándar de Yang-Mills arrojó luz sobre el mecanismo de confinamiento visto como un efecto de violación de la invariancia de Lorentz (LIV).

Testing Lorentz invariance with neutrino bursts from supernova neutronization
, 2013 Quantum-gravity (QG) effects might generate Lorentz invariance violation by the interaction of energetic particles with the foamy structure of the space-time. As a consequence, particles may not travel at the universal speed of light.

Lorentz invariance and quantum gravity: an additional fine-tuning problem? [PDF]
, 2004 Trying to combine standard quantum field theories with gravity leads to a breakdown of the usual structure of space-time at around the Planck length, 1.6*10^{-35} m, with possible violations of Lorentz invariance.

Probing of violation of Lorentz invariance by ultracold neutrons in the Standard Model Extension
Physics Letters B, 2019 We analyze a dynamics of ultracold neutrons (UCNs) caused by interactions violating Lorentz invariance within the Standard Model Extension (SME) (Colladay and Kostelecký (1997) [3] and Kostelecký (2004) [1]).

, 2016 We discuss the effect of hypothetical violation of Lorentz invariance at high energies on the formation of atmospheric showers by very-high-energy gamma rays.

LORENTZ INVARIANCE VIOLATION MATRIX FROM A GENERAL PRINCIPLE [PDF]
Modern Physics Letters A, 2010 We show that a general principle of physical independence or physical invariance of mathematical background manifold leads to a replacement of the common derivative operators by the covariant co-derivative ones. This replacement naturally induces a background matrix, by means of which we obtain an effective Lagrangian for the minimal standard model ...

Sensitivity to CP discovery in the presence of Lorentz invariance-violating potential at T2HK/T2HKK
European Physical Journal C: Particles and FieldsThe investigation of conservation/violation of conjugation and parity (CP) symmetry in the leptonic sector is essential to understanding the evolution of the universe. Lorentz invariance and CPT are fundamental symmetries of nature.

Aspects of phase-space noncommutative quantum mechanics
Physics Letters B, 2015 In this work some issues in the context of Noncommutative Quantum Mechanics (NCQM) are addressed. The main focus is on finding whether symmetries present in Quantum Mechanics still hold in the phase-space noncommutative version. In particular, the issues

Extra dimensions and Lorentz invariance violation [PDF]
Physical Review D, 2007 We consider effective model where photons interact with scalar field corresponding to conformal excitations of the internal space (geometrical moduli/gravexcitons). We demonstrate that this interaction results in a modified dispersion relation for photons, and consequently, the photon group velocity depends on the energy implying the propagation time ...
