Potential sensitivities to Lorentz violation from nonbirefringent modified Maxwell theory of Auger, HESS, and CTA
arXiv:1008.1967 · doi:10.1103/PhysRevD.82.105024
Abstract
Present and future ultra-high-energy-cosmic-ray facilities (e.g., the South and North components of the Pierre Auger Observatory) and TeV-gamma-ray telescope arrays (e.g., HESS and CTA) have the potential to set stringent bounds on the nine Lorentz-violating parameters of nonbirefringent modified Maxwell theory minimally coupled to standard Dirac theory. A concrete example is given how to obtain, in the coming decennia, two-sided bounds on the eight anisotropic parameters at the 10^{-20} level and an upper (lower) bound on the single isotropic parameter at the +10^{-20} (-10^{-16}) level. Comparison is made with existing and potential direct bounds from laboratory experiments.
