Simulating electromagnetic cascades with Lorentz invariance violation [PDF]

Classical and Quantum Gravity, 2023
Lorentz invariance violation (LIV) is a phenomenon featuring in various quantum gravity models whereby Lorentz symmetry is broken at high energies, potentially impacting the behaviour of particles and their interactions.

Neutrino Oscillations and Lorentz Invariance Violation [PDF]

Universe, 2020
This work explores the possibility of resorting to neutrino phenomenology to detect evidence of new physics, caused by the residual signals of the supposed quantum structure of spacetime.

CPT and Lorentz-invariance violation [PDF]

Hyperfine Interactions, 2009
The largest gap in our understanding of nature at the fundamental level is perhaps a unified description of gravity and quantum theory. Although there are currently a variety of theoretical approaches to this question, experimental research in this field

Constraining Lorentz Invariance Violation with Fermi [PDF]

CPT and Lorentz Symmetry, 2010
A cornerstone of special relativity is Lorentz Invariance, the postulate that all observers measure exactly the same photon speeds independently on the photon energies.

Neutrino Lorentz invariance violation from cosmic fields

Physics Letters B
From a cosmological perspective, scalar fields are well-motivated dark matter and dark energy candidates. Several possibilities of neutrino couplings with a time-varying cosmic field have been investigated in the literature.

Lorentz Invariance Violation in Modified Gravity [PDF]

Physics Letters B, 2012
We consider an environmentally dependent violation of Lorentz invariance in scalar-tensor models of modified gravity where General Relativity is retrieved locally thanks to a screening mechanism.

Hiding Lorentz Invariance Violation with MOND [PDF]

Physical Review D, 2011
Ho\v{r}ava gravity is a attempt to construct a renormalizable theory of gravity by breaking the Lorentz Invariance of the gravitational action at high energies.

Lorentz Invariance Violation and IceCube Neutrino Events [PDF]

Journal of High Energy Physics, 2015
The IceCube neutrino spectrum shows a flux which falls of as $E^{-2}$ for sub PeV energies but there are no neutrino events observed above $\sim 3$ PeV. In particular the Glashow resonance expected at 6.3 PeV is not seen.

MACRO constraints on violation of Lorentz invariance [PDF]

Nuclear Physics B - Proceedings Supplements, 2007
The energy spectrum of neutrino-induced upward-going muons in MACRO has been analysed in terms of relativity principles violating effects, keeping standard mass-induced atmospheric neutrino oscillations as the dominant source of $\nu_{\mu} \to \nu_{\tau}$
