Lorentz violation in Finsler geometry

J Zhu, BQ Ma - Symmetry, 2023 - mdpi.com
Lorentz invariance is one of the foundations of modern physics; however, Lorentz violation
may happen from the perspective of quantum gravity, and plenty of studies on Lorentz …

Electroweak standard model with very special relativity

J Alfaro, P González, R Avila - Physical Review D, 2015 - APS
The very special relativity electroweak Standard Model (VSR EW SM) is a theory with SU (2)
L× U (1) R symmetry, with the same number of leptons and gauge fields as in the usual …

Graviton mass bounds in very special relativity from binary pulsar's gravitational waves

A Santoni, J Alfaro, A Soto - Physical Review D, 2023 - APS
In this work we study the gravitational radiation produced by a Keplerian binary system
within the context of very special linear gravity (VSLG), a novel theory of linearized gravity in …

Photon mass in very special relativity

J Alfaro, A Soto - Physical Review D, 2019 - APS
In very special relativity (VSR) a gauge invariant photon mass is allowed. We explore some
consequences of keeping this parameter not zero. VSR-Maxwell equations are presented. In …

A bstract Mandelstam-Leibbrandt (ML) regularization of Very Special Relativity (VSR)
amplitudes in momentum space depends on two fixed null vectors n μ,\({\overline {n}} …

Self-Consistent Stochastic Finite-Temperature Modelling: Ultracold Bose Gases with Local (s-wave) and Long-Range (Dipolar) Interactions

NP Proukakis, G Rigopoulos, A Soto - arXiv preprint arXiv:2407.20178, 2024 - arxiv.org
We formulate a generalized self-consistent quantum kinetic theory including thermal
fluctuations and stochastic contributions for modelling ultracold Bose gases interacting via a …

Induced non-Abelian Chern–Simons effective action in very special relativity

Z Haghgouyan, M Ghasemkhani, R Bufalo… - The European Physical …, 2022 - Springer
In this paper, we study the one-loop induced effective action for a non-Abelian gauge field in
the very special relativity (VSR) framework in a\((2+ 1)\)-dimensional spacetime. We show …

Vacuum polarization and induced Maxwell and Kalb-Ramond effective action in very special relativity

RV Maluf, GJ Olmo - Physical Review D, 2023 - APS
This work investigates the implications of very special relativity (VSR) on the calculation of
vacuum polarization for fermions in the presence of Maxwell and Kalb-Ramond gauge fields …

New physics in spin entanglement

M Duch, A Strumia, A Titov - arXiv preprint arXiv:2403.14757, 2024 - arxiv.org
We propose a theory that preserves spin-summed scattering and decay rates at tree level
while affecting particle spins. This is achieved by breaking the Lorentz group in a non-local …

[HTML][HTML] Very special relativity and Lorentz violating theories

J Alfaro, VO Rivelles - Physics Letters B, 2014 - Elsevier
Very special relativity (VSR) keeps the main features of special relativity but breaks
rotational invariance. We will show how VSR like terms which depend on a fixed null vector …
