trans-GZK Cosmic Rays: Strings, Black Holes, Neutrinos, or All Three?
arXiv:hep-ph/0409029 · doi:10.1016/j.nuclphysbps.2004.10.011
Abstract
We review the scenario in which ``strongly interacting neutrinos'' are responsible for inducing airshowers with inferred energies eV. This possibility arises naturally in string excitation models having a unification scale effectively decoupled from the Planck scale. We then show that phenomenological quantum gravity considerations reveal an equivalency of ``mini-black hole'' and strongly interacting neutrino pictures for explaining trans-GZK events. This equivalence can be exploited to predict single particle inclusive distributions. The resulting observable consequences in airshower development are studied using the Adaptive Longitudinal Profile Shower (ALPS) simulation.
