Long Lived Superheavy Dark Matter with Discrete Gauge Symmetries
K. Hamaguchi, Yasunori Nomura, T. Yanagida
The recently observed ultra-high energy (UHE) cosmic rays beyond the Greisen-Zatsepin-Kuzmin bound can be explained by the decays of some superheavy particles forming a part of…

Superheavy Dark Matter with Discrete Gauge Symmetries
K. Hamaguchi, Yasunori Nomura, T. Yanagida
We show that there are discrete gauge symmetries protect naturally heavy X particles from decaying into the ordinary light particles in the supersymmetric standard model. This make…
