Possible astrophysical probes of quantum gravity
A satisfactory theory of quantum gravity will very likely require modification of our classical perception of space-time, perhaps by giving it a 'foamy' structure at scales of order the Planck
Letter: Ultra-High Energy Cosmic Rays and Symmetries of Spacetime
High energy cosmic rays allow probing phenomena that are inaccessible to accelerators. Observation of cosmic rays, presumably protons, with energies beyond 4 × 1019eV, the so-called
Testing Violations of Lorentz Invariance with Cosmic-Rays
Cosmic rays are the highest energy particles available for our study and as such serve as excellent probes of the effects of Lorentz Invariance Violations, which are expected to increase with energy.
Search for exotic contributions to atmospheric neutrino oscillations
The energy spectrum of neutrino-induced upward-going muons in MACRO has been analyzed in terms of effects of violating relativity principles, keeping standard mass-induced atmospheric neutrino
Constraining Lorentz Violation in Electroweak Physics
For practical reasons, the majority of past Lorentz tests has involved stable or quasistable particles, such as photons, neutrinos, electrons, protons, and neutrons. Similar efforts in the
“Exotic” Neutrino Oscillations
In the last few years, large underground cosmic ray detectors have reported consistent deficits of atmospheric muon neutrino fluxes and variations of the angular distributions compared to Monte Carlo
Astrophysical Neutrinos in Testing Lorentz Symmetry
An overview of searches related to neutrinos of astronomical and astrophysical origin performed within the framework of the Standard-Model Extension is provided. For this effective field theory, key
Lorentz invariance violation in top-down scenarios of ultrahigh energy cosmic ray creation
The violation of Lorentz invariance (LI) has been invoked in a number of ways to explain issues dealing with ultrahigh energy cosmic ray (UHECR) production and propagation. These treatments, however,

The nearly simultaneous arrival of the photons and neutrinos after a journey of some 160 000 yr shows that the limiting velocity of electron antineutrinos is equal to that of light to an accuracy approx.2 x 10/sup -9/, which provides an important new test of relativity and probes the structure of spacetime on intergalactic scales.
Possible violation of the equivalence principle by neutrinos.
The atmospheric neutrino data imply the same size violation of the equivalence principle as do the solar neutrinos data, and a formalism for describing such effects is justified.
Can the Sun shed light on neutrino gravitational interactions?
It is found that the Sun's gravitational field would amplify any small breakdown in the universality of the gravitational coupling by many orders of magnitude, and the differing energy dependences of the two level-crossing mechanisms can be used as a very sensitive tool to test the conventional universality hypothesis.

The laboratory limits on the neutrino oscillation process can be interpreted as tests of the equivalence principle in the quantum-relativistic regime, and put severe constraints on a maximal violation of this Principle in the case of massless neutrinos coupled to the Earth's gravitational field.
Indication of Anisotropy in Electromagnetic Propagation over Cosmological Distances
We report a systematic rotation of the plane of polarization of electromagnetic radiation propagating over cosmological distances. The effect is extracted independently from Faraday rotation, and
Modern Tests of Special Relativity
From our perspective one hundred years after the fact, the null result of the Michelson‐Morley ether‐drift experiment clearly marked the beginning of the end for the Newtonian notions of absolute
Lorentz noninvariance and the Eötvös experiments.
Using the present experimental limits from the Eoetvoes experiments, a limit is derived on the magnitude of a possible violation of Lorentz invariance in the model of Nielsen and Picek (NP).
Highest Energy Cosmic Rays
Recent work on highest energy cosmic rays is reviewed. The items discussed are: (1) experimental techniques, (2) anisotropies at the highest energies, (3) mass composition, (4) energy spectrum, (5)
A search for anisotropy of inertial mass using a free precession technique
The idea that the inertial mass of a body may a.rise from a gravitational coupling with distant matter has led to suggestions that the concentration of matter near the centre of our galaxy may result
