Lorentz invariance violation in top-down scenarios of ultrahigh energy cosmic ray creation
arXiv:hep-ph/0306288 · doi:10.1103/PhysRevD.69.085001
Abstract
The violation of Lorentz invariance (LI) has been invoked in a number of ways to explain issues dealing with ultrahigh energy cosmic ray (UHECR) production and propagation. These treatments, however, have mostly been limited to examples in the proton-neutron system and photon-electron system. In this paper we show how a broader violation of Lorentz invariance would allow for a series of previously forbidden decays to occur, and how that could lead to UHECR primaries being heavy baryonic states or Higgs bosons.
