Vacuum Cherenkov radiation in spacelike Maxwell-Chern-Simons theory
arXiv:0704.3255 · doi:10.1103/PhysRevD.76.025024
Abstract
A detailed analysis of vacuum Cherenkov radiation in spacelike Maxwell-Chern-Simons (MCS) theory is presented. A semiclassical treatment reproduces the leading terms of the tree-level result from quantum field theory. Moreover, certain quantum corrections turn out to be suppressed for large energies of the charged particle, for example, the quantum corrections to the classical MCS Cherenkov angle. It is argued that MCS-theory Cherenkov radiation may, in principle, lead to anisotropy effects for ultra-high-energy cosmic rays (UHECRs). In addition, a qualitative discussion of vacuum Cherenkov radiation from a modified-Maxwell term in the action is given, together with UHECR bounds on some of its dimensionless "coupling constants."
