The Photon Dispersion as an Indicator for New Physics?
The Photon Dispersion as an Indicator for New Physics?
We first comment on the search for a deviation from the linear photon dispersion relation, in particular based on cosmic photons from Gamma Ray Bursts. Then we consider the non-commutative space as a theoretical concept that could lead to such a deviation, which would be a manifestation of Lorentz Invariance …
