Gamma-ray polarization constraints on Planck scale violations of special relativity
Luca Maccione, Stefano Liberati, Annalisa Celotti +2
Using recent polarimetric observations of the Crab Nebula in the hard X-ray band by INTEGRAL, we show that the absence of vacuum birefringence effects constrains O(E/M) Lorentz vio…

Cosmic-Ray Nuclei, Antiprotons and Gamma-rays in the Galaxy: a New Diffusion Model
C. Evoli, D. Gaggero, D. Grasso +1
We model the transport of cosmic ray nuclei in the Galaxy by means of a new numerical code. Differently from previous numerical models we account for a generic spatial distribution…

GZK photon constraints on Planck scale Lorentz violation in QED
Luca Maccione, Stefano Liberati
We show how the argument exploited by Galaverni & Sigl in Phys. Rev. Lett., 100, 021102 (2008) (see also arXiv:0708.1737) to constrain Lorentz invariance violation (LV) using Ultra…
