Title: TeV strings and ultrahigh-energy cosmic rays
Authors: Illana, José I.
Issue Date: 2001
Abstract: The origin and nature of ultrahigh-energy cosmic ray events, above the Greisen–Zatsepin–Kuzmin (GZK) cutoff energy, constitute a long-standing, unsolved mystery. Neutrinos are proposed candidates but their standard interactions with matter are too weak. In the context of a TeV-scale string theory, motivated by possible extra space dimensions, the neutrino–nucleon scattering is examined. Resonant string contributions increase substantially the standard model neutrino-nucleon cross section. Although they seem insufficient to explain the trans-GZK cosmic ray events, their effects might be detected in next experiments.
