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…
Science with the new generation high energy gamma- ray experiments
M. Alvarez, D. D'Armiento, G. Agnetta +197
This Conference is the fifth of a series of Workshops on High Energy Gamma- ray Experiments, following the Conferences held in Perugia 2003, Bari 2004, Cividale del Friuli 2005, El…
Gamma-ray and neutrino diffuse emissions of the Galaxy above the TeV
C. Evoli, D. Grasso, L. Maccione
In this contribution we will discuss recent results concerning the intensity and the angular distribution of the gamma-ray and neutrino emissions as should be originated from the h…
New constraints on Planck-scale Lorentz Violation in QED from the Crab Nebula
Luca Maccione, Stefano Liberati, Annalisa Celotti +1
We set constraints on O(E/M) Lorentz Violation in QED in an effective field theory framework. A major consequence of such assumptions is the modification of the dispersion relation…
