Polarization mesurements of gamma ray bursts and axion like particles
Andre Rubbia, Alexander Sakharov
A polarized gamma ray emission spread over a sufficiently wide energy band from a strongly magnetized astrophysical object like gamma ray bursts (GRBs) offers an opportunity to tes…
Probes of Lorentz Violation in Neutrino Propagation
John Ellis, Nicholas Harries, Anselmo Meregaglia +2
It has been suggested that the interactions of energetic particles with the foamy structure of space-time thought to be generated by quantum-gravitational (QG) effects might violat…
Quantum-Gravity Decoherence Effects in Neutrino Oscillations: Expected Constraints from CNGS and J-PARC
Nick E. Mavromatos, Anselmo Meregaglia, Andre Rubbia +2
Quantum decoherence, the evolution of pure states into mixed states, may be a feature of quantum-gravity models. In most cases, such models lead to fewer neutrinos of all active fl…
Erratum (astro-ph/0510172): Robust Limits on Lorentz Violation from Gamma-Ray Bursts
John Ellis, N. E. Mavromatos, D. V. Nanopoulos +2
We correct the fitting formula used in refs. [1,2] to obtain a robust limit on a violation of Lorentz invariance that depends linearly on the photon energy. The correction leads to…
Constraining axion by polarized prompt emission from gamma ray bursts
A. Rubbia, A. S. Sakharov
A polarized gamma ray emission spread over a sufficiently wide energy band from a strongly magnetized astrophysical object like gamma ray bursts (GRBs) offers an opportunity to tes…
Probing quantum gravity using photons from a flare of the active galactic nucleus Markarian 501 observed by the MAGIC telescope
J. Albert et al., John Ellis, N. E. Mavromatos +3
We analyze the timing of photons observed by the MAGIC telescope during a flare of the active galactic nucleus Mkn 501 for a possible correlation with energy, as suggested by some…
