Berwald spacetimes and very special relativity [PDF]
Physical Review D, 2018 In this work, we study Berwald spacetimes and their vacuum dynamics, where the latter are based on a Finsler generalization of Einstein's equations derived from an action on the unit tangent bundle.

Homogeneously Modified Special relativity (HMSR) [PDF]
The European Physical Journal C, 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 ...

Triply special relativity [PDF]
Physical Review D, 2004 We describe an extension of special relativity characterized by {\it three} invariant scales, the speed of light, $c$, a mass, $ $ and a length $R$. This is defined by a non-linear extension of the Poincare algerbra, $\cal A$, which we describe here. For $R\to \infty$, $\cal A$ becomes the Snyder presentation of the $ $-Poincare algebra, while for $

Physics of Deformed Special Relativity: Relativity Principle revisited [PDF]
, 2004 In many different ways, Deformed Special Relativity (DSR) has been argued to provide an effective limit of quantum gravity in almost-flat regime. Some experiments will soon be able to test some low energy effects of quantum gravity, and DSR is a very ...

Observers and Their Notion of Spacetime beyond Special Relativity [PDF]
Symmetry, 2018 It is plausible that quantum gravity effects may lead us to a description of Nature beyond the framework of special relativity. In this case, either the relativity principle is broken or it is maintained. These two scenarios (a violation or a deformation

Very Special Relativity as a background field theory [PDF]
, 2016 We consider violation of Lorentz invariance in QED induced by a very high frequency background wave. An effective theory is obtained by averaging observables over the rapid field oscillations.

Some comments on the universal constant in DSR [PDF]
, 2006 Deformed Special Relativity is usually presented as a deformation of Special Relativity accommodating a new universal constant, the Planck mass, while respecting the relativity principle. In order to avoid some fundamental problems (e.g.

On the fragmentalist interpretation of special relativity
Philosophical Studies, 2018 Fragmentalism was first introduced by Kit Fine in his ‘Tense and Reality’ (Modality and tense: philosophical papers, Oxford University Press, Oxford, pp 261–320, 2005). According to fragmentalism, reality is an inherently perspectival place that exhibits

Beyond special relativity at second order [PDF]
, 2016 The study of generic, nonlinear, deformations of special relativity parametrized by a high-energy scale $M$, which was carried out at first order in $1/M$ in J. M. Carmona, J. L. Cort\'es, and F. Mercati, Phys. Rev.

Probing The Structure of Space-Time with Cosmic Rays [PDF]
, 2000 The study of the interactions of Cosmic Rays (CR's) with universal diffuse background radiation can provide very stringent tests of the validity of Special Relativity.
